Nephrology Fellows
Meet Our Nephrology Fellows
Nephrology fellows at Beth Israel Deaconess Medical Center are given opportunities for training in all aspects of kidney disease. Learn about the current fellows below.
First Year

Jose Mena was born and raised in the middle of the world Quito, Ecuador. He completed his medical school in his home country at Universidad Internacional del Ecuador. After graduation, he served as an associate professor and was in charge of several pharmacology and physiology lectures. Years later, he moved to the United States and completed his Internal Medicine residency at Mass General Brigham - Salem Hospital. He has numerous clinical interests and has published a few Internal Medicine related case reports on unique cases such as a stroke secondary to Polycythemia Vera, non-exertional heat stroke, and more. Dr. Mena also took part in multiple Grand Rounds during residency where he spoke about Cardiorenal Syndrome, AKI in COVID-19 patients and Palliative Care for CKD patients. He had the honor to be part of Kidney STARS during 2019 Kidney Week at Washington DC and in 2020-2021 he served as Chief Medical Resident at MGB-Salem Hospital after residency.

Catalina was born in Colombia. She completed her Medical Degree at Universidad de los Andes, Colombia, where she developed an interest for nephrology and clinical research. She then completed a year of postdoctoral training as research fellow at the Mayo Clinic. There she participated in the development of a morphometric analysis of biopsies from kidney transplant recipients. Subsequently, she completed her Internal Medicine residency at Icahn School of Medicine at Mount Sinai Beth Israel. During her training, she was awarded Resident of the Year 2020 by the National Hispanic Medical Association. She now joins the BIDMC family as a nephrology fellow. She wishes to pursue a career as a clinician-researcher. She has a special interest in transplant nephrology and diabetic kidney disease.

Voravech Nissaisorakarn was born and raised in Suratthani, Thailand. He received his education at Thammasat University, Pathumthani, Thailand and completed residency at Jacobi Medical Center, Bronx NY for PGY-1 and MetroWest Medical Center, Framingham, MA for PGY2-3. He has published a number of academic papers and is interested in transplant, non-invasive biomarker for rejection, growing kidneys, gene editing, and dialysis.

David was born in India, and was raised in San Antonio, Texas. He studied cell and molecular biology at the University of Texas at Austin before deciding to go to India for medical school. After medical school, he had the opportunity to work as a renal resident at Fortis Hospital, New Delhi, where he fell in love with the world of nephrology. He then relocated to Michigan where he completed his internal medicine residency training at McLaren Health Care - Michigan State University. During residency, he was awarded the PGY-1 Intern of the Year (2019), the PGY-2 Resident of the Year (2020) and the PGY-3 Consummate Physician of the Year (2021) awards. He also served as the chief resident in his final year of residency. David has a passion for teaching and education which led him to receive the Outstanding Resident Teacher Award from the 2021 medical school graduating class of Michigan State University. He is now thrilled to be joining the nephrology program here at BIDMC. He is especially interested in medical education, quality improvement, POCUS and interventional nephrology.
Second Year

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.
Third Year

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.
Fourth Year

Research Fellow

Transplant Fellow

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.
