Regina Zambrano

Regina Zambrano, MD
2007-2010

I was born, raised and attended Medical School in Barranquilla, Colombia. After obtaining my MD degree from Universidad del Norte, I moved to the United States to pursue a career in Pediatrics and Medical  Genetics. I completed my Pediatrics residency training at LSUHSC in New Orleans, Louisiana. Early in life I decided to become a physician, and becoming a Clinical Geneticist has been my goal ever since. My main interests are dysmorphology, birth defects, and the significance of minor congenital anomalies in the healthy child, prenatal diagnosis and newborn screening programs.

I am very excited to be a part of the Medical Genetics training program at JHU, and I am looking forward to work hard towards becoming a skilled clinical geneticist.

Vinayak Kottoor, MD

Vinayak Kottoor, MD
2007-2010

My educational experience began with schooling in the Midwest followed by the study of molecular biology at Vanderbilt University then to the cosmopolitan city of Bangalore, India where a fascinating medical as well as cultural education ensued.  Most recently, I have completed a 4 year Internal Medicine and Pediatrics residency in Saint Louis and an additional year as Chief Resident of Pediatrics.  Following upon these mind-broadening life experiences, the pleasure of interacting with a multitude of teachers (including my patients) and an abiding desire throughout to ‘make a difference’, I am looking forward to strengthening my educational foundation in the Medical Genetics program at Johns Hopkins University.  My interests are broad with my clinical experiences thus far having motivated me to the area of complex genetics and the interplay of genetic predisposition and environmental variables and newer avenues for intervention.  As clinical genetics evolves from determining destiny to finding ways to modify it, I feel privileged to be a part of this increasingly relevant field.

Current Combined Internal Medicine/
Genetics Resident

Mark Zubriski

Mark
Zubriski,MD, PhD
2007-2012

I am very excited to be the first selected into the Combined Internal Medicine/Genetics Residency Program at the Johns Hopkins University.  I will be completing my MD from the University of Arizona as well as PhD from Arizona State University in Molecular and Cellular Biology by the summer of 2007.

As an undergraduate at UCLA, I studied multiple endocrine neoplasia and Huntington disease at the molecular level.  In graduate school, I studied the effect single nucleotide polymorphisms on the genes involved in anti-viral host defense.  During medical school, I developed an insitu hybridization technique for the detection of a metalloprotease implicated in the metastasis of prostate cancer.  Finally, my PhD work focuses on studying the effect of oxidized LDL on monocytes and their contribution to atherosclerosis and CVD. 

I look forward to my training at Johns Hopkins to further educate me on the many facets of genetics while continuing to develop my knowledge within human molecular genetics and its application towards medical care.

Hilary Vernon

Hilary
Vernon, MD, PhD
2005-2010

In January of 2004 I completed my PhD in Molecular Genetics from Rutgers University, New Brunswick, NJ and in May of that year graduated from the Robert Wood Johnson Medical School, UMDNJ, Piscataway, NJ. 

I am planning to pursue a career in pediatric genetics with both clinical and research components. I have been involved in genetics based research since I was a sophomore in college. My research has ranged from a genome mapping project at the National Human Genome Research Institute and a deletion mapping project at the Children’s Hospital of Philadelphia while an undergraduate, to a lizard population study in the Pine Barrens of New Jersey and a cytogenetics study at Robert Wood Johnson University Hospital while in medical school, to my Ph.D. work in kidney stone diseases and to my current post-doctoral work. Genetics is the most fascinating branch of research to me, and is at the root of so many pediatric diseases. It is the perfect research branch with which to combine clinical and research medicine.

Amr Al-Saif

Amr Al-Saif
2004-2007

Molecular Geneticist

I graduated with an MBBS in 2001 from the College of Medicine, King Faisal University in Saudi Arabia, after which I spent one year as an intern. From 2002-2004 I was hired as an assistant scientist at the King Faisal State Hospital and Research Center, Riyadh, Saudi Arabia.  Since 2004
I have been a Clinical Molecular Genetics Postdoctoral Fellow, in the Institute of Genetic Medicine, Johns Hopkins University.  I am currently doing research in the laboratory of Dr. Nicholas Katsanis. 

Non coding RNA (ncRNA) species play a significant role in the biology of both prokaryotic and eukaryotic cells. They have a wide spectrum of functions including regulatory, catalytic and structural, many of them are house keeping RNA molecules. A class of these ncRNAs is large mRNA like transcripts that are not predicted to code for proteins though they are highly conserved. I'm studying some species of this class by in vitro and in vivo assays to understand their nature of function and to develop suitable experimental methods that will aid in characterizing them in a wide scale in the future.

Finally I am also working on a disease with possible complex inheritance pattern called Fuchs Endothelial Corneal Dystrophy.
