I am a cell biologist and bioengineer, and my primary research focuses on the rapidly growing area of cell mechanics and mechanotransduction: the role that mechanical forces play in regulating cellular function from healthy to diseased phenotypes. (1) Cardiovascular Biology, Mechanics and Disease: Funding source: American Heart Association (7/1/2018–6/30/2021; PI) Cardiovascular disease (CVD) is the main cause of death globally. Arterial stiffness is associated with many CVD. The molecular mechanisms governing arterial stiffening and the phenotypic changes in vascular smooth muscle cells (VSMCs) associated with the stiffening process are key areas in cardiovascular biology, mechanics and disease. Evidence suggests that arterial stiffening can drive aberrant migration and proliferation of VSMCs within the vessel wall. Yet, the underlying mechanisms regulating vascular stiffening and the molecular changes within VSMCs associated with the stiffening process remain unclear. While medications reduce hypertension, none specifically target pathways directly related to arterial stiffness. The overall goal of work in my lab is to address this gap in our understanding by investigating how changes in arterial stiffness affect VSMC function and fundamentally contribute to the progression of CVD. This study also addresses an important concept in vascular tissue remodeling (the interaction between extracellular matrix stiffness and VSMC behavior). Methodologically, my lab use a novel approach to dissect the molecular mechanism in VSMCs: My lab combines methods for manipulating and measuring tissue and cell stiffness using atomic force microscopy and traction force microscopy for simultaneously modulating substrate stiffness and measuring contraction force by culturing cells on a compliant substrate that mimics in vivo mechanical environments of the VSMCs. (2) Smooth Muscle Cell (and Cancer Cell) Heterogeneity: Highly heterogeneous responses of VSMCs to arterial stiffness or CVD make it difficult to dissect underlying molecular mechanisms. To overcome this, my lab integrates Mechanobiology, Vascular Cell Biology, and Machine Learning to manipulate stiffness and assess responses with unique precision. Machine learning is used to deconvolve inter- and intra-cellular heterogeneity and identify specific subcellular traits that correlate with stiffness and VSMC behavior. My lab also applies Machine Learning approaches to identify specific breast cancer cell behaviors that respond to different stiffness conditions. (3) Optogenetics and Biophotonics in Stem Cell Biology: Funding source: National Science Foundation (8/1/2017–7/31/2020; co-PI) Major breakthroughs in the field of genomics, embryonic stem cell biology, optogenetics and biophotonics are enabling the control and monitoring of biological processes through light. Additional research in my laboratory focuses on developing a nanophotonic platform able to activate/inactivate gene expression and, thus, control stem cell differentiation in neuronal cells, by means of light-controlled protein-protein interactions. More specifically, the light-controlled molecular toggle-switch based on Plant Phytochrome B and transcription factor Pif6 will be utilized to control the nuclear fibroblast growth factor receptor-1, which is a master regulator of stem cell differentiation. Open Positions: The Bae lab is currently accepting graduate students through the Pathology Masters program (or other programs) as well as motivated undergraduates. For Graduate Students: I am looking for one or two graduate (MS) students who understand my research interests, have read my previous publications, and have their own (crazy!!!) ideas as to where my research efforts should be directed. All graduate students are required to complete and submit internationally recognized Journal article(s) before graduation from my lab. A Masters thesis should generate at least one first author publication. For Undergraduate Students: I encourage all UB undergraduates (with GPA 3.0 or higher) to get "hands on" experimental training in the sciences. An undergraduate research project tends to be part of a larger whole, but I make sure to include credit for students work in presentations and publications.

Protein phosphorylation is an essential mechanism by which intercellular signals regulate specific intracellular events. Protein kinases, the enzymes catalyzing protein phosphorylation reactions, represent a major superfamily of genes, collectively representing 2% of the protein coding potential of the human genome. Current projects in Dr. Edelman‘s lab are devoted to the role of protein kinases in prostate and ovarian cancer. These projects utilize a wide range of techniques and involve, collaboration with investigators at Roswell Park Cancer Institute to develop protein kinase-targeted therapies for both types of cancer.

As a neonatologist working in a neonatal intensive care unit (NICU), I care for the sickest and most premature infants. At the Oishei Children’s Hospital and Millard Fillmore Suburban Hospital, I collaborate with fellows, residents, medical students, nurse practitioners, nurses — and other health care professionals involved in the care of infants in the NICU — to help these fragile infants overcome severe challenges to grow and thrive. My research is focused on improving the quality of life of newborns. My studies in the area of resuscitation and pulmonary hypertension are nationally recognized. I operate one of the few centers in the country that includes a newborn lamb model with which to conduct research in the areas of resuscitation, delayed cord clamping and asphyxia. I have done extensive study in hypertension in term and premature neonates, resuscitation (relating to heart rate and oxygen exposure) and long-term effects of hyperoxia and bronchopulmonary dysplasia. My upbringing in India has given me a deep appreciation for global health issues relating to maternal and child health. That has spurred me to try to develop low-cost technologies to improve neonatal and child health in developing countries, with an emphasis on resuscitation and birth asphyxia. I mentor fellows and help them learn the skills and techniques they need to be successful neonatologists, either in an academic setting or in private practice. I utilize the flipped classroom, delivering instruction online outside of class and moving “homework” into the classroom. I provide fellows with the freedom and independence to succeed by offering opportunities to learn and practice technical skills and by guiding fellows’ growth with timely feedback. I have more than 50 publications to my credit, and I make it my business to help fellows get their own research published. My guidance helps fellows give successful presentations at regional and national conferences. In fact, my trainees have received multiple awards for their research presentations at the Eastern Society for Pediatric Research meetings over the years. I am committed to my fellows’ success as the next generation of compassionate, competent neonatologists.
