Ian Antón Oldenburg

Principal Investigator

Assistant Professor of Neuroscience and Cell Biology, RWJMS

Director of the CABM Program for Holographic and Optogenetic Biology

Ian received a B.S. in biology from Carnegie Mellon University. In 2014, he completed his Ph.D. in neuroscience at Harvard University under the supervision of Bernardo Sabatini, there he investigated the interactions between the basal ganglia and motor cortex. As a postdoctoral fellow in Hillel Adesnik’s lab at the University of California Berkeley he developed new multiphoton holographic optogenetic approaches and used them to dissect the interactions between neurons in sensory cortex.


In general, Ian is interested in understanding how neurons interact with each other to give rise to behaviors. However, these interactions can be diverse, depending heavily on context, and on the specifics of which neurons are firing when. In many cases, the first step to answer these questions is to build new tools that allow ever more precise manipulations.

Barbara Gruszka

PhD Student – Neuroscience

Barbara is a PhD student in the School of Graduate Studies Neuroscience Program at Rutgers – New Brunswick. Barbara graduated from Princeton University in 2020 with a degree in Neuroscience. For her undergraduate thesis work, Barbara worked in the Intelligent Performance and Adaptation (IPA) laboratory with Dr. Jordan Taylor. There, she designed a virtual reality throwing task and collected performance, motor, and eye-tracking data to further understand the effect of feedback-less practice movements on performance. After graduation, Barbara worked as a Pharmacology and Biomarkers Research Associate II for PTC Therapeutics, a company specializing in developing therapeutics for orphan diseases. In her free time, Barbara enjoys painting commissioned animal portraits, swimming, and refining her computer programming skills.

Raj Harsora

Research Technician

Raj is a Research Technician in the Oldenburg Lab in the Department of Neuroscience and Cell Biology. Raj completed his bachelors degree in the biological sciences at Rutgers University. In the past Raj has done work and research at the Sports Performance Lab and the Cancer Institute of New Jersey. Currently, Raj also works as a research assistant under Dr. Arigo at Rowan University, where he contributes to various projects revolving around clinical psychology, social psychology, etc. Raj hopes to pursue doctoral school in the near future as a stepping stone in his research journey! In Raj’s free time he enjoys working out, finding new places to eat,  and reading.

Masashi Hasegawa

Postdoctoral Researcher

Masashi is a postdoctoral fellow in the Oldenburg lab at Center for Advanced Biotechnology and Medicine. He originally studied experimental psychology and behavioral toxicology at Hokkaido University (Japan), then moved into systems neuroscience. He conducted his dissertation research, investigating the neural mechanisms underlying motor preparation and execution by using a two-photon microscope, at the Centre for Integrative Neuroscience, University of Tübingen, under supervision of Dr. Takashi Sato. As a postdoctoral fellow in Jan Gründemann lab at University of Basel (Switzerland) and German Center for Neurodegenerative Diseases (Germany), he established deep brain imaging techniques by using a GRIN lens, and investigated the neural plasticity of auditory thalamus across cross-modal sensory learning.

In the Oldenburg lab, Masashi will employ multiphoton holographic optogenetic approaches to uncover how neural ensemble activities give rise to specific behaviors.
