Specialty/Research Focus:
Cytopathology; Surgical Pathology

Research Summary:
As a pathologist in the Department of Pathology and Anatomic Sciences, my clinical duties are primarily in anatomic pathology, including surgical pathology, cytopathology and autopsy. In addition, an important part of our department’s mission is resident and medical student education and I participate formally, giving didactic lectures, and informally, in the gross room and at the microscope. During the course of my residency, I developed an interest in breast pathology as well as cytopathology, and both of these areas have become a focus of my clinical work today. Since joining the department in 2007, I have participated in the breast pathology service. I provide diagnoses and prognostic information to assist in the appropriate treatment of breast diseases. Being a member of a subspecialty service has allowed me to develop relationships with surgeons and oncologists, which, in turn, facilitates better care for patients. After practicing pathology for several years and observing some of the inefficiencies that exist in the medical system, I became interested in applying process improvement principles to the laboratory. I have completed a certificate course in Lean Six Sigma through Villanova University, and participate in the department’s Process Improvement committee. After receiving my medical degree from the University at Buffalo School of Medicine in 2001, I completed a residency in Anatomic and Clinical Pathology and a fellowship in Cytopathology at Cleveland Clinic. I am board certified in Anatomic and Clinical Pathology and Cytopathology.

Specialty/Research Focus:
Anatomic Pathology; Pediatric Pathology; Surgical Pathology; Autopsy

Research Summary:
I am a surgical pathologist with nearly twenty years of experience and specialty expertise in Pediatric Pathology. I gained first entrance into this career field at the main pediatric teaching hospital affiliated with Medical University in Warsaw, Poland and continued my training in Pediatric Pathology at the Cincinnati Children‘s Hospital Medical Center, followed by practice at the Hopital Ste Justine in Montreal and Children‘s Hospital at Scottish Rite in Atlanta. My clinical and academic focus involves responsibilities related to the surgical pathology sign-out service at Women and Children‘s Hospital of Buffalo, teaching of the residents and fellows, participating in the Anatomic Pathology core lecture series for Pathology Residency Program, multiple interdepartmental conferences at Women and Children‘s Hospital as well as Neonatology-Pathology Morbidity & Mortality meetings. I am active in the pediatric tumor board conferences shared by both Women and Children‘s Hospital and Roswell Park Cancer Center. My interests are focused on diagnosis of pediatric pathologic disorders affecting children of all ages, with emphasis on pediatric gastrointestinal and liver disorders and pediatric neoplasms. Clinical service at Women and Children‘s Hospital of Buffalo allowed me to expand my interests in recent years to encompass fetal, neonatal and placental pathology. I also sign out autopsies, gynecologic and non-gynecologic cytology and I offer expert consultation from outside institutions in the area of Pediatric Pathology. I am participating in the ongoing NASH and other pediatric GI tract disorder research projects carried out in collaboration with the Division of Pediatric Gastroenterology and Nutrition and in research studies on experimental necrotizing enterocolitis (NEC) with the Division of Neonatology.

Specialty/Research Focus:
Anatomic Pathology; Blood Banking/Transfusion Medicine; Clinical Pathology; Cytopathology; Hematology - Clinical Pathology; Immunopathology; Surgical Pathology; Toxicology; Transfusion Medicine; Bioinformatics; Microbiology; Virology

Research Summary:
I serve the Department of Pathology and Anatomic Sciences as a general pathologist in anatomic and clinical pathology. My primary areas for service work include surgical pathology and cytopathology as an attending pathologist rotating among the Kaleida hospital sites and clinical pathology activities in clinical chemistry, transfusion medicine, microbiology and hematology. I serve as the laboratory medical director for the clinical laboratories at the Women and Children‘s Hospital of Buffalo and the Center for Laboratory Medicine, Williamsville (Flint). I also provide more specialized medical support for the forensic toxicology laboratory at the Women and Children‘s Hospital, the fetal defect screening program at the Center for Laboratory Medicine in Williamsville, the Virology laboratory at Women and Children‘s Hospital and the Therapeutic Plasmapheresis program at the Buffalo General Medical Center. I have developed an interest in Clinical Informatics and regularly employ those skills to retrieve and analyze data from Kaleida and elsewhere to support clinical decision making, research activities, EHR development and business development. Within the department, I am the pathologist overseeing the Transfusion Service across Kaleida and also provide pathology direction to the Kaleida Clinical Chemistry and Microbiology programs. In addition, I support the leadership of Kaleida in their Utilization Program, the Gainsharing Program, Peer Review and as Chair of the Site specific Transfusion Committees. Since January 2013 I have also served as the laboratory director of the Erie County Public Health Laboratory. Previously I have served as the laboratory director at the Center for Laboratory Medicine, Amherst (Suburban), Buffalo General Hospital and as an assistant laboratory director at Gates Circle. Each of these positions has been valuable to me in learning how different groups work together and how different groups of clinicians see and set expectations for a pathology department. Outside of Kaleida, I serve the region as representative to the Erie County Medical Society Legislative Committee and the Economic Affairs Committee. I have also served as president of the Western New York Society of Pathologists (1999-2000) and as Delegate to the College of American Pathologists House of Delegates (2005 - present). The overall theme of these activities is to leverage the skills cultivated by any practicing pathologist to recognize patterns. Those patterns recognized are then directed to purposes that can be quite diverse, ranging from diagnosis to data integrity. Data retrieved from multiple sources are used to provide an unbiased review for departmental and hospital leaders to troubleshoot, drive test menus or to review patterns of practice. Good data can drive good decisions, but only to the degree that the data can be recognized and understood. My professional time is divided in four parts, with anatomic pathology service work comprising about one quarter of my time, clinical pathology service work a second quarter, administrative activities a third quarter and clinical informatics the last quarter (plus or minus 5%), but with the added bonus that on any one day, these duties can shift dramatically to address the needs of the department and hospital. One of the most rewarding parts of my career has been the opportunity do all of these to the best of my ability and to support the efforts of the excellent professionals around me. The variety of responsibilities I have translate into a job that is never dull. I have used my own situation as a model for the pathology residents I train to provide a live demonstration that the field of Pathology is big enough to have something of interest for any interested person.

Liu, Weiguo, MD, PhDClinical Assistant Professor
Email: wliu2@buffalo.edu
Phone: 859-2140

Specialty/Research Focus:
Surgical Pathology

Research Summary:
I have broad interests in pathology with special interests in oncologic surgical pathology and gastrointestinal pathology. After graduating from medical school and practicing general surgery for a couple of years, I enrolled in a Ph. D program at Roswell Park Cancer Institution in the department of molecular pharmacology and cancer therapeutics to fulfill my interest in finding tumor makers that can help to diagnose cancer earlier and to develop target therapy to improve cancer patients’ life quality. I finished my Ph. D program successfully with a couple of publications and a patent. Realizing that pathology is the best specialty that can help me to combine my research interests with clinical practice, I did four years’ pathology residency training at State University New York at Buffalo followed two years’ fellowship training at Memorial Sloan Kettering Cancer Center. These trainings not only helped me to develop excellent clinical skills but also provided me with good opportunities to perform translational research. I regard that my career is composed of three major parts and it is in these three parts that I have set my career goals and been working hard to achieve them. The first is clinical service. As a well-trained and board certified pathologist on anatomic and clinical pathology, I practice general surgical pathology and some clinical pathology. I corporate with clinicians to provide high-quality clinical service to our patients for the management of their diseases. The second is research. I think research is the most important way to help us keep practicing up-to-date medicine. The fast developing advanced techniques provide us with many opportunities to improve our clinical practices. Currently, I continue working on a project I started during my fellowship which is using next generation sequencing to analyze genomic alternations in ampullary carcinoma. I am also interested in evaluating liver fibrosis by using quantitative image analysis tools. The university and department of pathology provide great research opportunities. The third is teaching. I have been actively involving in teaching medical students and residents during my residency and fellowship training and I really enjoy it. Now my teaching activities include core lectures, signing out cases with residents and giving unknown conferences.

Phone: (716) 568-3705

Specialty/Research Focus:
Anatomic Pathology; Surgical Pathology

Research Summary:
I am a board certified pathologist in both anatomic and clinical pathology. I practice general surgical pathology as well as some clinical pathology. My area of expertise is breast and gynecological pathology. I completed a fellowship at University of Pittsburgh Medical Center (UPMC), Magee Hospital, where I studied both breast and gynecological pathology and was able to participate in their active consult service. Working in a place with so many breast/gyn. cases has really helped me in my diagnostic skills today. I also enjoy participating in the multidisciplinary breast conference where we discuss challenging patient cases and look at many aspects of patient care including pathology, radiology, oncology, and surgery. I also have an interest in teaching residents and medical students. I give some of the core curriculum lectures to our pathology residents in my areas of interest. I also work with residents when they are rotating through the surgical pathology service. I spend some of my time doing research predominantly in breast and gyn. areas. I especially enjoy clinical research and working with colleagues from other specialties.

Phone: (716) 859-2140

Specialty/Research Focus:
Anatomic Pathology; Clinical Pathology; Molecular Genetic Pathology - Clinical Biochemical; Surgical Pathology

Research Summary:
Professional Summary: As a pathologist, I help cover the clinical duties for the Kaleida Health system’s anatomical pathologist needs at the Buffalo General Medical Center, Suburban Hospital and DeGraff Hospital. I am Board certified in Anatomic and Clinical Pathology with an interest in oncologic pathology and approaches related to precision medicine. The majority of my time is allocated for clinical service work, which includes general surgical pathology, some clinical pathology coverage, and the teaching of pathology residents. Additional clinical duties include overseeing the laboratory’s immunohistochemistry section and involvement in the build-up of the CTRC’s biobank. For resident education, one major emphasis currently being undertaken is the deciphering of the technical and bioinformatic bridges that separate pathologists from those involved in the field of genomic sequencing. Dedicated research time has allowed me to be involved in investigations with several different collaborators on sample enrichment, and how it effects downstream molecular and proteomic studies. Recent work has scrutinized regional gene expression profiles in an attempt to map cancer field effects and identify biomarkers for colon cancer. Current investigations are centered on designing microscale sample preparation methods to allow for combinatorial evaluation of diminuitive core biopsy specimens. This is a little thought of, but key element that fulfills a stated need from basic scientists and would extend the utility of such specimens for de novo assembly methods currently in development. A number of other investigations also exist, and are in different levels of progress, but all trace back to a sequence/ genomic context in relation to precision medicine.

Specialty/Research Focus:
Anatomic Pathology; Autopsy; Clinical Pathology; Cytopathology; Dermatopathology - Anatomic Pathology; Immunopathology; Medical Microbiology; Surgical Pathology; Bioinformatics; Microbiology

Research Summary:
I pursued undergraduate and graduate education in biomedical engineering because of my interest in the application of basic science to solve real world problems. My studies included biomaterials and medical imaging. An interest specifically in medical science led me to medical school and eventually into pathology. After close to four years practicing community pathology, a desire to reestablish connections with UB pathologists initiated during my Roswell Park fellowship brought me back to Buffalo as a UB pathologist. My clinical responsibilities include surgical pathology, cytopathology, autopsy pathology and clinical pathology. I routinely work with pathology residents during their surgical pathology, cytology and autopsy rotations. I have particular interest in dermatopathology and gastrointestinal pathology. Image processing and analysis and bioinformatics also intrigue me. I am currently searching for new opportunities to collaborate with faculty in the anatomical sciences half of our department.

Phone: 716-829-2846

Specialty/Research Focus:
Immunopathology; Surgical Pathology; Renal Pathology

Research Summary:
Patient care for a Pathologist is centered on assisting patients and clinicians in the understanding and the use of clinical laboratory data for the planning of therapeutic decisions. My personal specialty focus areas are in renal pathology, immunopathology, and urological pathology. I provide tissue biopsy and clinical laboratory diagnose , prognoses, and therapeutic advice to patients and clinicians on medical and surgical diseases of the kidney (including kidney transplants), bladder, prostate , and testis. These services include the interpretation of biopsies and pathology specimens, consultations on the ordering and/or the results of clinical laboratory lab tests. Raised in Philadelphia, PA I received my undergraduate education from LaSalle College in Philadelphia in 1973. I attended the University Of Pennsylvania School Of Medicine and received my MD in 1977. After finishing medical school I did an internship in Internal Medicine at Pennsylvania. I completed my Pathology Residency in anatomic and clinical pathology at the Hospital of the University of Pennsylvania in 1982. During that training I had special concentrations in immunology, HLA testing, and nephropathology. I was a Fellow in Surgical Pathology in 1982-1983. I joined the faculty in the Department of Pathology and Laboratory Medicine at the University of Pennsylvania in 1983. In my first year of appointment I was given the opportunity to do a specially arranged fellowship with Dr Conrad Pirani in Nephropathology at Columbia University. At Penn I rose through the ranks to become Professor, Vice Chair for Anatomic Pathology-Hospital Services, and Interim Chair of the Department of Pathology and Laboratory Medicine My research interests are translational and have been focused in the domain of genitourinary pathology. Over the last decade I have had the great opportunity to work collaboratively with a group of image scientists in the development of quantitative image analysis tools tailored to the needs of the digital pathology community. Our vision is to create a new analytic paradigm fusing the data from the quantitative analysis of high resolution images with multidimensional molecular data. This “fused diagnostics” approach will support personalized predictive modeling of disease and its response to therapy. Our collaborative group is funded and is working hard to develop platforms which will support this new way of addressing complex multivariable testing. Over the years I have had the great good fortune to teach many classes of undergraduate medical students in nephropathology and genitourinary pathology. I have been Program Director of the Surgical Pathology and Immunopatholgy Fellowships at the Hospital of the University of Pennsylvania and instructed 56 Fellows. I have been a member of 9 PhD and 1 MS candidates’ thesis committees. I continue to instruct at the UME, GME, and Graduate student levels. I have been active in the work of many Pathology societies both as a speaker and in varied leadership roles. My volunteer work has been with the ACSP, USCAP, CAP, Pathology Informatics, ASIP, ICPI, and APC. I was a member of the ASCP Board of Directors for many years and rose through the leadership sequence to be elected ASCP President for 2010-2011. My society work has helped me understand both the challenges and the opportunities which face our profession in these times of great change. In 2011 I moved from Philadelphia to Buffalo to become Chair of Pathology and Anatomical Sciences at the University at Buffalo, State University of New York. I continue to maintain an active collaborative research program in image science and focus my efforts as Chair on building our clinical, educational, and research programs at UB. I am excited to be part of this great University which is on the rise.
