Nephrology Fellows

Parvathy Krishna Geetha is a first year renal fellow here at BIDMC. She did all her schooling in India, including medical school at TD Medical College in Kerala, India. Dr. Geetha moved to US in 2016 to do an elective rotation at Memorial Hermann Hospital in Texas. After that, she joined St. Elizabeth’s Medical Center, Boston for 3 years of Internal Medicine Residency. Right from the beginning of residency, Dr. Geetha was fascinated by nephrology, which brought her to BIDMC for 2 years of clinical fellowship. During her 2nd/research year of fellowship, she is planning to focus mostly on basic science/translational research. In her future career, Dr. Geetha hopes to work in an academic setting, as she does not want to miss out on either the clinical aspect nor on research elements in Nephrology.

Periklis Kyriazis is a first-year Clinical Fellow. He earned his MD from Charles University in Prague and completed his Internship and Residency at Baystate Medical Center/University of Massachusetts in 2020. His clinical interests include Immunological Tolerance in Organ Transplantation, gene expression profiling in optimization of immunosuppression, chemotherapy-related complications in the kidney and collecting duct, and palliative care in ESRD with a focus in illness trajectories.

Subhash Paudel is originally from Nepal and he graduated from Tribhuvan University in 2010. After graduating from medical school, he came to the United States for further training and joined the Internal Medicine residency at St. Vincent Hospital in Worcester, Massachusetts. He worked as a hospitalist at Rhode Island Hospital and at Saint Vincent Hospital before joining the Nephrology fellowship at Beth Israel Deaconess Medical Center. Subhash enjoys forging longitudinal relationships with his patients and is looking forward to a career in Nephrology. He is especially interested in the field of palliative care Nephrology in the CKD population. He wants to use his expertise in Nephrology to expand kidney care in the western part of Nepal.

Krishna Agarwal is currently a 2nd year Nephrology Fellow, graduating into the Kidney Transplant Fellowship starting in the summer of 2021. He was born in Delhi, India and went to medical school at Vardhman Mahavir Medical College & Safdarjung Hospital in Delhi. After completing medical school, he joined Prof. Terry Strom as a Research Fellow in his Immunology lab at Beth Israel Deaconess Medical Center in 2014. They conducted experiments to identify immunoregulatory cells that could help develop tolerance to a transplanted organ and prevent rejection, and also identified a unique population of immunoregulatory macrophages in the pancreas, downregulation of which was associated with onset of autoimmune diabetes mellitus. After completing his fellowship in 2016, he started his medical residency at the University of Massachusetts Medical School's Baystate campus in Springfield, MA. Krisha is primarily interested in clinical research aimed at prolonging the life of a transplanted organ, thereby achieving the goal of “one organ for life.” Currently, he is working with a team of researchers at the Transplant Institute to identify optimal blood pressure targets for kidney transplant recipients which would minimize adverse cardiovascular outcomes and prolong the transplant’s life. Their work has been accepted for an oral presentation at the American Transplant Congress 2021.

Larissa is originally from Brazil, where she completed her medical school. She has since been around New England, and completed her residency at University of Connecticut, where she was also chief resident. She absolutely loves all things kidney and medical education. She hopes to go to as many Red Sox games as she can.

Ruth is originally from Los Angeles and moved to Boston for undergraduate studies at Brandeis University. She completed medical school at Tufts University School of Medicine and her Internal Medicine residency at University of Maryland. She couldn't stay away from her favorite city and is thrilled to be back in Boston and doing her fellowship training at BIDMC. She has wanted to become a Nephrologist since the 2nd year of medical school when she realized how fun it is to work up and treat acid-base and electrolyte derangements. She is also interested in clinical education and was drawn to BIDMC by the outstanding educators in this department. In her spare time, she is an avid foodie, baker, lover of all things outdoors, Greek mythology connoisseur, and world traveler.

Esi graduated from medical school in Albania at Faculty of Medicine, Tirana. She embarked in a journey to the US where she spent some time at the bench, doing immunology research, particularly targeting transplant rejection, studying regulatory T.cells as a mean of immune tolerance in transplant, urinary exosomes, and novel drugs targeting immunoproteasome. She then completed her Internal medicine residency at Saint Elizabeth Medical Center and has now joined Nephrology Fellowship at BIDMC. In her free time she likes to spend time with her husband and son. She enjoys learning new languages, exploring Boston, the cultural diversity and everything the city has to offer.

Nate originally hails from Arlington, VA. He did his undergraduate studies at Dartmouth College in New Hampshire where he graduated Cum Laude and was a Presidential Scholar. He attended medical school at Icahn School of Medicine at Mount Sinai in New York City, where he graduated with a distinction in research and was the recipient of numerous awards including Outstanding MPH Thesis Award (2013), the George James Epidemiology Award (2014), and the Gold Humanism Society (2015). He joined BIDMC for his residency in internal medicine. His research interests revolve around the epidemiology and pathophysiology of chronic kidney disease in populations with unique risk factors, with a particular focus on chronic kidney disease of nontraditional cause (CKDnt) in Central America. His recent work has focused on a metabolomic approach to understanding pathophysiologic change in response to stress. Nate has also published a number of studies in conjunction with colleagues at MIT using large databases to address questions about clinical management of common kidney disorders in ICU populations, including sodium and acid-base derangements and AKI. He serves as board chairman of La Isla Foundation, a nonprofit dedicated to addressing the CKDu epidemic, particularly in Central America. Nate lives with his partner, Sarah and his dog, Simon. He is an avid hiker, canoeist, and general lover of all things outdoors.

Joshua Waitzman, MD, PhD, is a fourth-year research fellow, working in the laboratory of Dr. Martin Pollak with interests in basic science research, clinical care, and education. He is from West Hartford, Connecticut and completed his undergraduate education at Brown University. He earned his medical degree from the Feinberg School of Medicine at Northwestern University where he also earned his PhD and completed his residency at McGaw Medical Center, Northwestern University. In his research, Dr. Waitzman uses structural biology and biochemistry techniques to determine how the high-risk variant APOL1 proteins cause disease. He is the recipient of several awards and honors including the Ben Lipps Fellowship from the American Society of Nephrology (2020), Alpha Omega Alpha (2015), the Fannie and John Hertz Foundation Fellowship (2010), the Morris Povar Prize in Biotechnology and Physiology (2007), and Phi Beta Kappa (2007). Outside of the lab, he is active in nephrology social media and is a discussant on the Channel Your Enthusiasm podcast. Dr. Waitzman is the proud parent of a six-year-old, and enjoys Pixar movies, running, and trying takeout from new restaurants.

Min Zhuo graduated from Peking University, China. She worked at Peking University First Hospital for two years as an internal medicine resident. She completed her internal medicine clinical training at Cook County Hospital and joined the BIDMC nephrology fellowship in 2017. She is keenly interested in clinical research in nephrology. Her previous research focused on peritoneal dialysis, contrast-induced nephropathy and kidney disease awareness. Her current research is pharmacoepidemiology of diabetic nephropathy drugs. She has three children, who always keep her busy.

Sandy graduated from Faculty of Medicine Siriraj Hospital, Bangkok Thailand and spent a couple of years at the bench side where she delved into the world of Proteomics. She investigated target protein antigens in Lupus Nephritis and the role of bacteria in Calcium oxalate stone formation. She then completed her internal medicine residency at Jacobi Medical Center, Albert Einstein College of Medicine before joining the Nephrology Fellowship at BIDMC. In her free time, she is an avid foodie and loves nothing more than to lounge at home with her husband and baby.
