The Sullivan Lab
PEOPLE
Bill Sullivan, Ph.D.: PRINCIPAL INVESTIGATOR
Dr. Sullivan obtained his Ph.D. in Cell & Molecular Biology from the University of Pennsylvania in 1997. His graduate work, performed in the lab of Dr. David Roos, focused on using novel genetics tools to probe mechanisms of drug resistance in Toxoplasma. After a postdoc at Eli Lilly & Co, he became an Assistant Scientist under the mentorship of Dr. Sherry Queener at the Indiana University School of Medicine (IUSM) to examine gene regulation in Toxoplasma. He is currently Showalter Professor at IUSM in the Department of Pharmacology & Toxicology and the Department of Microbiology & Immunology. Dr. Sulivan served on the AOIC study section at NIH from 2016-2019. Dr. Sullivan is an editor/writer at PLOS SciComm and serves on the Editorial Board of mSphere and ASBMB Today. He is also the author of the book, "Pleased to Meet Me: Genes, Germs, and the Curious Forces That Make Us Who We Are," published by National Geographic. Sullivan has been featured in a wide variety of outlets, including CNN, Fox & Friends, The Doctors, Science Fantastic with Dr. Michio Kaku, Doctor Radio, and more. He has published over 100 papers in scientific journals and has written for The Washington Post, National Geographic, Discover, Scientific American, COSMOS, Psychology Today, The Conversation, and more.
Michael Holmes, Ph.D.: POSTDOCTORAL FELLOW
Dr. Michael Holmes obtained his Ph.D. in Biochemistry from the University of Windsor in 2015. His graduate work, performed in the laboratory of Dr. Sirinart Ananvoranich, focused on the study of developmentally regulated transcript-specific translational repression in Toxoplasma gondii bradyzoites. Mike joined the Sullivan lab in July, 2015 and is working on understanding how changes in translational control relate to the tachyzoite - bradyzoite interconversion process.
Sandeep Srivastava, Ph.D.: POSTDOCTORAL FELLOW
Dr. Sandeep Srivastava obtained his Ph.D. in Molecular Medicine from Jawaharlal Nehru University, New Delhi, India. His graduate work was performed in the laboratory of Professor Suman Kumar Dhar, focused on biochemical and functional analysis of Silent Information Regulator protein (SIR2) in Plasmodium falciparum. In 2014, he joined the laboratory of Professor Mark Featherstone at Nanyang Technological University, Singapore to investigate AP2 transcription factors in the malaria parasite. Dr. Srivastava joined the Sullivan lab in March 2017 and is analysing the function of AP2 transcription factors in Toxoplasma.
Vishakha Dey, Ph.D.: POSTDOCTORAL FELLOW
Vishakha received her PhD in Molecular Parasitology under the supervision of Prof. Swati Patankar from IIT Bombay, India. Her doctoral studies revolved around understanding nuclear trafficking in Plasmodium falciparum. She joined the Sullivan Lab in March 2020 and is studying the role of GCN5 lysine acetyltransferase complexes in Toxoplasma.
Matheus Bastos, Ph.D.: POSTDOCTORAL FELLOW
Dr. Bastos obtained his Ph.D. in Agricultural Biochemistry (focused on biochemistry and molecular biology) from the Federal University of Viçosa in 2014. His graduate work, performed in the lab of Dr. Juliana Fietto, studied the role of NTPDases in purinergic signaling and virulence in the protozoan parasite Leishmania. He then completed postdoctoral studies on a project entitled anti-parasitic drug discovery in epigenetics (2014-2016, Juliana Fietto Lab). From 2016-2019, he worked in the laboratory of Dr. Luiz R.O. Tosi (University of São Paulo) investigating DNA repair mechanisms in Leishmania. Matheus joined the Sullivan Lab in August 2020 to study the role of mRNA modifications and translation control in Toxoplasma gondii.
Aasutosh Tripathi, Ph.D.: POSTDOCTORAL FELLOW
Aashutosh completed his Ph.D. in the laboratory of Dr. Sunando Datta at the Indian Institute of Science Education and Research Bhopal (IISERB), where his study focused on characterizing the effector of Rab21 in Entamoeba histolytica and deciphering its role in actin cytoskeleton modulation. He joined the Sullivan lab in March 2021 and is working on understanding the translation control in Toxoplasma gondii.
