Director
Allan Doctor, MD
Professor of Pediatrics

adoctor@som.umaryland.edu
Allan Doctor, MD, directs the Center for Blood Oxygen Transport and Hemostasis (CBOTH), which addresses fundamental, challenging questions related to blood O2 transport and hemostasis, from a systems perspective, with attention to human biology, physiology and therapeutics. Doctor is Professor of Pediatrics at the University of Maryland School of Medicine (UMSOM) in Baltimore. Prior to coming to Baltimore, he led the Division of Pediatric Critical Care Medicine at Washington University School of Medicine in St. Louis (WUSOM) as a Professor of Pediatrics for 10 years prior to stepping down to focus on his expanding research program and ErythroMer development.
Doctor is a Co-Founder and the Chief Scientific Officer of KaloCyte, where he leads the company’s scientific research and development efforts for ErythroMer, a novel bio-inspired artificial red blood cell.
Doctor is internationally recognized for his research on the role of red blood cell-based signaling in the control of regional blood flow, related pathophysiology arising from acquired red cell injuries, blood substitute design, and on novel approaches to clinical decision making and translational transfusion medicine in the setting of critical illness.

Stephen Rogers, PhD
Assistant Professor

Stephen.rogers@som.umaryland.edu
Dr. Rogers is an exercise scientist/physiologist and red blood cell biochemist by training. His work focuses on the role of red blood cells (RBCs) in the modulation of regional blood flow to match oxygen (O2) delivery to metabolic demand. More specifically, how RBCs contribute to O2 delivery homeostasis by controlling NO bioavailability in a fashion that links vascular tone to biochemical cues of perfusion sufficiency. His current focus is on dysregulation to this important RBC based O2 delivery homeostatic mechanism in disease states (i.e. sepsis, diabetes, sickle cell), which appears to play a significant role in disease amplification and related morbidity progression. In addition to his work as a research scientist in Dr. Doctor’s laboratory, Dr. Rogers is the director of the Red Blood Cell Characterization Core at CBOTH.
Mary Brummet, MS
Lab Manager

Mbrummet@som.umaryland.edu
Mary Brummet is the laboratory manager for Dr. Allan Doctor’s laboratory at Center for Blood Oxygen Transport and Hemostasis. She received her MS in Biotechnology from Johns Hopkins University with a concentration in molecular biology and cell signaling. Her current focus is on red cell physiology in disease states as well as implementing laboratory policies and safety procedures. She values a career where her passion for science can give her the opportunity to improve human health such as diabetes, SCD and sepsis. In her free time she likes to cook and spend time with family and friends along with her two Great Danes.
Tobi Rowden, RN
Clinical Research Nurse
410-706-7068
trowden@som.umaryland.edu
Tobi Rowden is the Clinical Research Nurse for Dr. Allan Doctor’s Research Team at the University of Maryland School of Medicine at the Center for Blood Oxygen Transport and Hemostasis (CBOTH).
Tobi completed her nursing education and training in Canada. She moved to Texas shortly thereafter to begin her career in nursing. Tobi has worked for some of the largest children’s healthcare systems in Texas, North Carolina, and California. Her nursing career consists of extensive knowledge and practice in Pediatric Intensive Care, Nurse Management, and Pediatric Research. Tobi brings 23 years of nursing knowledge and experience to the Doctor Team. She has participated and successfully coordinated many Clinical Research Trials with her proficiency in critical thinking, organizational, and communication skills. Most notably, she took part in a successful novel drug clinical trial for pediatric sepsis and hypovolemic shock.
Tobi participates in the coordination and implementation of Dr. Doctor’s Research Studies. She ensures that patients meet protocol goals and compliance, collects clinical data, sample collection, and review of clinical laboratory data. She assists in providing evidence-based research that is essential to safe and quality nursing care. Tobi’s goal has always been focused on successful outcomes for pediatric patients and research participants.
Zohreh Safari, PhD
Post Doc Fellow
443-687-1035
zsafari@som.umaryland.edu
Dr. Zohreh Safari is the post-doctoral fellow for Dr. Allan Doctor's laboratory at the Center for Blood Oxygen Transport and Hemostasis (CBOTH). Her background, education, publication record and experience include cell biology, molecular genetics and bioengineering, angiogenesis with particular focus upon vascular biology of the microcirculation during hypoxia. She received her Bachelor's degree in Biology from Tabriz University. She then received her Master's degree at Tabriz University in 2013 with a concentration in the extensive impacts of hypoxia on the anticancer mechanisms of metformin. She began her training at Tarbiat Modares University, where she earned her PhD in 2019.
The major emphasis of her PhD was on extracellular and vascular niches and investigated their potential in inducing neovascularization as a treatment for infectious diseases. In addition, evaluation of angiogenesis responses based on induction of environmental signals. Furthermore, her research had concentrated upon blood cell include white blood cell (immune cell) and red blood cell their responses into philological stress.
Additionally, Dr. Safari has designed a scaffold. This scaffold causing increased blood vessel growth and angiogenic factor that lead to increase angiogenesis.
