Meet Our Team...
Mark Kohr, PhD, FAHA
Mark received his PhD in Integrated Biomedical Science from The Ohio State University in 2009 with a specific focus in cardiovascular physiology. Mark pursued additional training as a NRSA-funded postdoctoral fellow with a joint appointment in the laboratories of Dr. Elizabeth ‘Tish’ Murphy at the National Heart, Lung and Blood Institute and Dr. Charles Steenbergen at Johns Hopkins University School of Medicine. With the support of a Pathway to Independence Award (K99/R00) from the National Heart, Lung and Blood Institute and a Beginning-Grant-In-Aid Award from the American Heart Association, Mark established the Kohr Laboratory of Cardiovascular Redox Signaling, as a tenure-track Assistant Professor in the Department of Environmental Health and Engineering in the Johns Hopkins Bloomberg School of Public Health in 2015. When not in the lab, Mark enjoys spending time with his wife and two sons, playing golf, and cheering on the Orioles and the Ravens.
Oby Ebenebe, PhD
Oby completed her PhD in Physiology at the University of Otago (New Zealand), training with Dr. Jeff Erickson. Her thesis was focused on the sex-differential and postmenopausal role of CaMKII in atherosclerotic plaque progression. In 2019, Oby joined the Kohr Laboratory of Cardiovascular Redox Signaling, which recently discovered a role for S-nitrosoglutathione reductase (GSNO-R) in the cardioprotection of female hearts from ischemic injury, as a postdoctoral research fellow. Currently, Oby is examining the role of GSNOR in the context of pre-clinical models of ischemic heart disease in postmenopausal females.
Nicole Taube, BS
Nicole is originally from Kalamazoo, MI and graduated from the University of Michigan in 2018 with a BS in Ecology and Evolutionary Biology and a minor in Environment, and is currently a PhD student in the Toxicology, Physiology and Molecular Mechanisms graduate program in the Department of Environmental Health and Engineering. Joining the Kohr Laboratory of Cardiovascular Redox Signaling in 2019, Nicole's work seeks to examine the epigenetic impact of gestational arsenic exposure on the cardiovascular system. When not in the lab, Nicole enjoys hiking, being outside, and reading books.
Raihan Kabir, BS
Kabir grew up in South Burlington, Vermont and graduated from Johns Hopkins University in 2018 with a BS in Molecular & Cellular Biology. Kabir is currently a Master of Science Degree (ScM) student with a focus on Human Toxicology and Pathophysiology in the Department of Environmental Health and Engineering. Kabir joined the Kohr Laboratory of Cardiovascular Redox Signaling in 2018 and his research seeks to examine the mechanistic impact of arsenic exposure on the cardiovascular system and ischemic heart injury. When not in lab, Kabir enjoys venturing anywhere with a good view and eating ice cream.
Prithvi Sinha, MHS
Prithvi is originally from Mumbai, India and graduated from Vellore Institute of Technology in 2017 with a degree in Biotechnology and Johns Hopkins Bloomberg School of Public Health with an MHS in Biochemistry and Molecular Biology. Prithvi joined the Kohr Laboratory of Cardiovascular Redox Signaling in 2018. His research is currently focused on investigating TRIM72 as a cardioprotective agent in response to ischemia-reperfusion injury. In his free time, Prithvi enjoys watching movies, listening to music, playing squash and indulging in TV shows. He is also a total foodie and loves experimenting in the kitchen, although extremely unpredictable when it comes to producing edible food.
Former Lab Members
Kevin Casin, BS
Kevin joined the Kohr Laboratory of Cardiovascular Redox Signaling in 2015 as a PhD student. His research investigated the molecular mechanisms and physiology of sex-dependent differences in cardioprotection from ischemia-reperfusion injury. Kevin’s work focused primarily on the importance of S-nitrosoglutathione reductase (GSNOR), a critical regulator of protein S-nitrosation, in the female myocardium. Kevin is currently a postdoctoral fellow at Emory University in Atlanta, GA.
Undergraduate Research Assistant
Tiffany joined the Kohr Laboratory of Cardiovascular Redox Signaling as a freshman at Johns Hopkins University majoring in Global Environmental Change and Sustainability (GECS) with an interest in gender and sexuality, public health, and art. Tiffany is now an undergraduate student at the University of Texas.
Emily Illingworth, BS
Emily joined the Kohr laboratory in 2018 as a rotating PhD student in the Toxicology, Physiology and Molecular Mechanisms graduate program in the Department of Environmental Health and Engineering. Emily is currently a PhD student in the laboratory of Dr. Fenna Sille.
Ryne Veenema, BS
Ryne joined the Kohr Laboratory of Cardiovascular Redox Signaling in 2016. Ryne is originally from upstate New York and graduated from Cornell University in 2016 with a BS in Environmental and Sustainability Sciences, and Johns Hopkins Bloomberg School of Public Health with an ScM in Human Toxicology and Pathophysiology. Ryne’s research characterized the sex-dependent effects of arsenic exposure on myocardial ischemic injury. Ryne is currently a medical student at SUNY Downstate Medical Center in Brooklyn, NY.
Nathan Mackowski, MS
Research Technologist (2016-2018)
Nathan joined the Kohr Laboratory of Cardiovascular Redox Signaling in 2016. Nathan is originally from San Francisco and graduated from Case Western Reserve University in 2012 with a BA in Evolutionary Biology and Political Science, and Johns Hopkins University with a MS in Biotechnology in 2018. His research focused on elucidating the role of S-nitrosation in the regulation of TRIM72 stability during cardioprotection. Nathan is currently a PhD student at the Pasteur Institute in Paris, France.
Qin Shao, MD, PhD
Visiting Fellow (2013-2015)
Qin joined the Kohr laboratory in 2013 as a Visiting Fellow from China. Qin is currently a Cardiologist at Renji Hospital and an Associate Professor at Shanghai Jiaotong University School of Medicine.
Jonathan Fallica, PhD
Postdoctoral Fellow (2015-2016)
Jon received his PhD from the Department of Environmental Health and Engineering in the Johns Hopkins Bloomberg School of Public Health in 2015, and joined the Kohr lab as a postdoctoral fellow shortly thereafter. Jon is currently a Toxicologist at the Food and Drug Administration (FDA).
Summer Intern (2017)
Ashley was a summer intern in the Kohr lab during the summer of 2017 as a part of the Pulmonary and Critical Care Medicine Summer Internship Program. Ashley graduated from Cornell University in 2019, majoring in Molecular and Cell Biology. Ashley plans to enroll in medical school in the Fall of 2020.
Amanda St. Paul
Summer Intern (2017)
