Biography:

Nikolaos P. Daskalakis, MD, PhD, is the director of the Neurogenomics and Translational Bioinformatics Laboratory at McLean Hospital and an assistant professor of psychiatry at Harvard Medical School. He is also an affiliate member of the Broad Institute, MIT Computer Science and Artificial Intelligence Laboratory, and the National Center for PTSD. Dr. Daskalakis received his MD from the University of Athens, his PhD in neuropsychopharmacology from Leiden University, and completed post-doctoral research fellowships in clinical neuroendocrinology at Leiden University and in systems biology at the Icahn School of Medicine.

Dr. Daskalakis focuses on the interaction between stress and the brain, conducting translational studies and following an integrative systems biology approach. His lab uses transcriptomic and epigenomic profiling of brain and blood samples to identify gene networks associated with vulnerability and resilience to PTSD. Dr. Daskalakis leads the Systems Biology working group of the Psychiatric Genomics Consortium for PTSD. He is an editor for Brain Sciences and Frontiers (in Behavioral Neuroscience, Endocrinology, Neuroscience, and Psychiatry).

Research Focus:

Combining his training as a medical doctor with his expertise as a translational neuroscientist and data scientist, Dr. Daskalakis conducts research focused on the connection between stress and brain functions. Dr. Daskalakis’ Neurogenomics and Translational Bioinformatics Laboratory employs functional genomics to dissect functional epigenetic and cell-type-specific regulatory elements and risk loci underlying the genetics of stress-related mental disorders, such as PTSD, and then engages in translational research using cell culture and animal models to validate causal gene and variants.

In addition, the lab employs “big data” and machine learning to investigate genotype-to-phenotype relationships related to complex neuropsychiatric traits to gain a deeper understanding of the individual differences in the expression of symptoms. Dr. Daskalakis and his lab pursue research on these fronts and, ultimately, seek to identify novel mechanisms and treatments for these devastating mental disorders.

Recently, Dr. Daskalakis was awarded the Jonathan Edward Brooking Mental Health Research Fellowship and the Brain & Behavior Research Foundation NARSAD Young Investigator Award to support his research on the role and regulation of the gene for SNRNP35, a small nuclear ribonucleoprotein involved in U12 splicing, in stress-related mental disorders.
