Biography  
Dr. Marenco is a Psychiatrist and researcher at the Intramural Research Program at the National Institute of Mental Health. He completed his MD at the University of Genova, Italy, followed by training in Clinical Neurophysiology, and a residency in Psychiatry at the University of Maryland and the NIMH-IRP. He has had further research training at Johns Hopkins University, Department of Nuclear Medicine, with Dean Wong and at the Clinical Brain Disorders Branch (CBDB), NIMH-IRP, under the supervision of Daniel Weinberger.

In 2004 he became a staff clinician, helping run several inpatient and outpatient studies in CBDB at the NIMH-IRP, then continued in the Clinical and Translational Neuroscience Branch under Karen Berman in 2011 and became Deputy Director of the Human Brain Collection Core (HBCC) with Barbara Lipska in 2016. He has been Acting Director of HBCC since 2020.

Dr. Marenco has broad interests in neurophysiology, neurodevelopment, genomics and biomarkers of mental illness, particularly schizophrenia.

Scientific Interests  
Dr. Marenco has broad experience with a full spectrum of methodology to study brain physiology, neurological and psychiatric disorders. He has conducted clinical trials, and used brain imaging in vivo (PET, EEG, fMRI, MR spectroscopy, DTI) and genomic techniques postmortem to characterize abnormalities in psychiatric patients and attempt to understand their genetic and environmental roots. His focus has been especially on schizophrenia research, but this has expanded to other disorders since joining HBCC.

Biography 
Pavan Auluck, MD, PhD, is a neuropathologist and Acting Deputy Director of the Human Brain Collection Core (HBCC). His research focuses on understanding the cellular heterogeneity in the human brain and how this cellular and molecular heterogeneity may be altered in psychiatric disorders. Dr. Auluck completed his undergraduate studies in Biology at the Massachusetts Institute of Technology, his graduate and medical training at the University of Pennsylvania Perelman School of Medicine, his pathology and neuropathology residency at the Massachusetts General Hospital, and post-doctoral training at the Whitehead Institute for Biomedical Research. Dr. Auluck joined the HBCC in 2017.

Research Interests 
The Human Brain Collection Core is tasked with collecting and distributing high-quality, well-characterized brain tissue from individuals with psychiatric disorders and neurologically-intact individuals. The HBCC collaborates with investigators across the NIH and distributes tissue to extramural investigators. In addition, Dr. Auluck is focused on deciphering the molecular changes associated with psychiatric disorders with the ultimate goal of identifying a pathological biomarker. To this end, the HBCC has embarked on an effort to characterize brain regions implicated in the pathophysiology of schizophrenia and major depression and to investigate psychiatric disorders at a single-nucleus level and spatial transcriptomic level.
