Current Fellows
Lindsay Harrison, M.D.
Fellow Year Three
I am a native Texan who completed undergrad at SMU in mechanical engineering, medical school at UT Houston, and residency in Internal Medicine at UT Southwestern Medical Center. I enjoy running, swimming, playing board games, gardening, and reading. I am undecided in what to focus on specifically but am interested in bone health, PCOS, and obesity/metabolism.
Neema Chokshi, M.D.
Fellow Year Two
I grew up in Houston, but went to medical school here at UT Southwestern. After completing my residency in Internal Medicine at the University of Illinois at Chicago, I came back to UT Southwestern for my fellowship. Although all of Endocrinology interests me, I plan to pursue a research project involving diabetes and metabolism. In my spare time, I enjoy fitness and cooking.
Christopher Hudak, M.D.
Fellow Year Two
I grew up in the suburbs of North Dallas and went to college at the University of Texas at Austin. I finished medical school at Texas A&M HSC College of Medicine and recently completed residency training at the University of Virginia. In my professional life I am interested in purusing research in diabetes and in my personal life I enjoy watching movies and sports, reading, travelling, and spending time with my family.
Anita Raghuwanshi, M.D.
Fellow Year Two
I grew up in New Jersey, did my undergraduate studies at Harvard in Biomedical Engineering, and attended Medical School at Albert Einstein College of Medicine in New York City. Looking for a change of atmosphere, I came to Dallas and completed Internal Medicine residency at UTSW and stayed on for Endocrine Fellowship. I've wanted to become an Endocrinologist since I was five-years-old. I haven't decided on a focus of research yet because I love all of Endocrinology! As a clue to my personality, my nurses call me "The hugging doctor." In my spare time (which is nonexistent), I enjoy competitive ballroom dancing, singing, acting, and writing poetry.
Christoph Zechner, M.D., Ph.D.
Fellow Year Two
I was born and raised in Germany and completed my medical and doctoral training at the Albert Ludwig University of Freiburg. After a medical internship in Germany, I took on a postdoctoral fellowship in the laboratory of Dr. Daniel P. Kelly at Washington University in St. Louis where I investigated the roles of transcriptional coactivators PGC-1 alpha and beta in skeletal muscle. Before coming to UT Southwestern, I moved with Dr. Kelly to Orlando, FL, to complete my postdoctoral fellowship at the new Sanford-Burnham Medical Research Institute at Lake Nona. As my next step, I decided to move to UT Southwestern to complete my training in internal medicine and endocrinology as a member of the physician scientist training program. I plan to stay engaged in basic science research in the area of energy metabolism and I am excited to work in the lab again next year. In my spare time, I enjoy playing and watching soccer, bike riding, exploring new foods and drinks and taking advantage of all the great cultural opportunities that Dallas offers, especially the symphony and the opera.
Marconi Abreu, M.D.
Fellow Year One
Marconi is from Brazil, where he started his medical training. He moved to Farmington, CT to complete his residency at University of Connecticut, where he also served as Chief Resident. During residency he was presented the Pamela Kisluk Spirit Award 2006-2007 for unparalleled ability to spread contagious enthusiasm, passion, happiness, and positive attitude toward patients and peers. From 2008 through now he has worked in River Fall, MA in a private practice where his practice was geared towards patients with diabetes.
His hobbies are playing the guitar and piano, teaching, and soccer. He just returned from a trip to his homeland, where he married his wife – a registered dietician.
Mariana Marin, M.D.
Fellow Year One
Mariana is from Caracas, Venezuela. She completed her residency program at Unity Health System, a University of Rochester affiliated hospital in Rochester, NY. During her residency she visited UT Southwestern for a one month away rotation which turned out to be very productive! Yes, she met her future husband during endocrinology consult rounds and they have a wedding planned this Fall. For the past year Mariana worked as a hospitalist in Waco, TX.
Markey McNutt, M.D.
Fellow Year One
Markey completed Summa Cum Laude his undergraduate studies in biomedical chemistry at Oral Roberts University in Tulsa, OK. He has been a “Southwesterner” ever since. He earned a dual M.D./Ph.D. degree working on PCSK9 in Dr. Horton’s laboratory and completed his 2-year Internal Medicine residency. He wants to “grow up” to be a scientist! He is married, and has a young son.
Anna VanderHeiden, M.D.
Fellow Year One
Anna was born in Poland, but grew up and studied medicine in Ukraine. She is fully trained in Adult and Pediatric Neurology in her home country – yet fell in love with Endocrinology while completing her Internal Medicine Residency at Texas Tech Odessa. She is married and has two sons, 10 and 11 years old. She is very talented at oil painting, and likes to ice skate.
