Postdoctoral Researchers

Tamara Andres, M.D. Ph.D.

Dr. Andres received her medical and doctoral degrees from the Albert-Ludwigs-University in Freiburg-Germany.  She currently works with Drs. Linda Chang and Vanessa Douet, providing clinical research support for several NIH-funded neuroimaging studies and clinical trials.  She is particularly interested in the biological mechanisms of affective disorders and substance abuse.

Deborrah Castillo, M.D.

Dr. Castillo completed her medical degree and training in the Philippines.  She is a pain management specialist.  Currently, she is enrolled as a graduate student in the Masters in Clinical Research (MSCR) program.  She is also conducting research with Dr. Linda Chang on several clinical studies, including the evaluation of working-memory training effects in HIV patients. In addition, she is conducting a thesis project to evaluate the relationship between pain symptoms and brain morphometry.

Michael Herbst, Ph.D.

Dr. Herbst received his Engineering Doctorate from the University Medical Center Freiburg, where he worked as a Ph.D. student in the Medical Physics group of Prof. Dr. Jürgen Hennig. He is the recipient of the Alexander von Humboldt Foundation Award, which currently supports his research and training with Dr. Thomas Ernst.  Together, they are working on motion-correction techniques for MRI studies and high-resolution diffusion weighted imaging.

  Ahnate Lim, Ph.D.

Dr. Lim received his Ph.D. in Cognitive Psychology from the University of Hawaii at Manoa.  He is currently working with Dr. Chang on several neuroimaging studies, using techniques such as functional MRI and morphometric analyses.  Some of these projects also involve the study of brain development and the effects of cognitive training. His current research interests include music cognition, computational models of behavior and neurophysiology, and the integrative role of cognitive resources such as working memory and attention.

Andrii Petrov, Ph.D.
Dr. Petrov received his Ph.D. in Mechanical Engineering from the University of Canterbury, New Zealand. He is conducting research under the supervision of Dr. Andy Stenger.   Their current research focuses on the development and application of accelerated spiral data acquisition methodologies and image reconstruction techniques based on combined low rank & sparse matrix completion for MRI, and their applications to neuroimaging.

Aditya Singh, Ph.D.

Dr. Singh received his Ph.D. in Electrical Engineering from the University of Hawaii at Manoa. He is currently working with Dr. Thomas Ernst on real time motion correction algorithms in MR scanner using a Moire Phase Tracking system.  His research interests include bio-medical electronics and systems, wireless bio-sensing, sensors and RF and microwave systems.
