Dr. Nestoras Mathioudakis is an Associate Professor of Medicine and Clinical Director of the Division of Endocrinology, Diabetes & Metabolism at the Johns Hopkins University School of Medicine. A board-certified endocrinologist, Dr. Mathioudakis focuses his clinical practice on the care of patients with endocrine disorders, with a particular clinical interest and research focus on diabetes mellitus. A core faculty member of the Johns Hopkins Armstrong Institute for Patient Safety and Quality, Dr. Mathioudakis’s main research focus is on discovering ways to improve patient safety and quality among hospitalized patients with diabetes. He is the Endocrine Director of the Johns Hopkins Multidisciplinary Diabetic Foot and Wound Clinic and is actively investigating the causes and treatment of diabetic foot ulcers. Dr. Mathioudakis graduated from the Johns Hopkins University School of Medicine and trained in Internal Medicine at Johns Hopkins Bayview Medical Center. He completed his fellowship in Endocrinology, Diabetes, & Metabolism at the Johns Hopkins Hospital and then joined the faculty in this division in 2012. He has served as the Clinical Director of the Division since 2016. Dr. Mathioudakis received his Master of Health Science degree in clinical investigation from the Johns Hopkins Bloomberg School of Public Health in 2015. He is currently the recipient of an NIH-funded grant to develop and evaluate a real-time informatics alert for prevention of insulin-associated hypoglycemia in hospitalized patients.
Mohammed S. Abusamaan, MD MPH, Postdoctoral Research Fellow
Dr. Abusamaan received his medical degree from Misr University in Egypt then pursued part of his internal medicine residency training at King Fahad General Hospital in Saudi Arabia. He earned a Masters degree in Public Health from the Johns Hopkins Bloomberg School of Public Health in 2017, with a focus on epidemiology and biostatistical methods for public health and clinical research. Prior to joining our lab, Dr. Abusamaan has been actively engaged in both basic science and clinical translational research at Wayne State University which resulted in several co-authored manuscripts. He worked on a randomized multi-center clinical trial in the Division of Gastroenterology & Hepatology at Johns Hopkins comparing clinical outcomes in patients undergoing differing endoscopic treatment approaches for the treatment of achalasia. Dr. Abusamaan’s primary research project in our lab is the development of a prediction model for iatrogenic hypoglycemia due to insulin treatment in hospitalized patients using advanced statistical modeling and machine learning methods.
Susan Langan, MS MPH, Biostatistician
Susan Langan is a biostatistician in the Division of Endocrinology, Diabetes & Metabolism. She received a Masters of Public Health Degree in Epidemiology at San Diego State Graduate School of Public Health and subsequently received a Master of Science in Biomedical Sciences/Tropical Medicine at the University of Hawai’i at Manoa. Susan has been at Hopkins for nearly two decades and has extensive experience conducting statistical analyses of observational studies and clinical trials.

Former Lab Members
Estelle Everett, MD, MHS, 2016-2019, Instructor of Medicine, University of California, Los Angeles
Dr. Estelle Everett completed a two-year research fellowship in our lab. Her research was focused predominantly on high-risk patients with type 1 diabetes (e.g. recurrent admissions for diabetic ketoacidosis). Her research culminated in five first-author and two co-author publications.
Betiel F. Voss, MD, MPH, 2016-2018, Endocrinologist, Aurora Health Care, Milwaukee, WI
Dr. Betty Fesseha Voss completed a two-year research fellowship in our lab. Her research was focused on exploring the association between glycemic control and wound healing in a prospective cohort of patients with diabetic foot ulcers. Her research culminated in a first-author publication in Diabetes Care.
Saira Khan, MD, 2015-2016, Endocrinologist, Associate Fellowship Program Director, Endocrinology; Allegheny Health Network, PA
Dr. Saira Khan’s research project in our lab was focused on glycemic outcomes occurring at the transition of care from home to hospital in insulin-treated patients. Her research culminated in a first-author publication in Diabetes Research and Clinical Practice.
Kyrstin Lane, MD, 2016-2018, Endocrinology Fellow, UCLA
Dr. Lane’s main research project in the lab was a systematic review and meta-analysis of glycemic control and wound healing in diabetic foot ulcers.
Gwendolyn Jack, MD, 2014-2015, Instructor in Medicine, Weill Cornell Medical College, Cornell University.
Dr. Jack worked on a project in our Diabetic Foot and Wound Clinic looking at the association between glycemic control and other clinical factors on wound outcomes. Her research contributions lead to a co-author publication in Diabetes Care.
Sayed M. Hosseini, MD, 2014-2015 Geriatric and Gerontology Fellow, University of Maryland School of Medicine.
Dr. Hosseini worked on data management and analysis in our prospective observational study of diabetic foot wound patients. His research contributions resulted in a co-author publication in Diabetes Care.
Han Na Kim, MD, 2016-2017, Clinical Associate, Endocrinology, Diabetes & Metabolism, Johns Hopkins University.
Dr. Kim’s primary research project in the lab was focused on the transition of care from hospital to home of diabetic patients. Specifically, she was interested in evaluating whether changes in blood glucose medications are made during hospitalization when appropriate, and whether such changes are linked to better outcomes in patients. Her work culminated in a co-author publication currently under review. In addition, Dr. Kim contributed to two book chapters in diabetes.
Dalilah Reyes de Jesus, 2017 NIDDK Summer Visiting Medical Student, MD Candidate, San Juan Bautista School of Medicine, Puerto Rico
