SSCC Staff

Scientific and Statistical Computing Core

SSCC is the Scientific and Statistical Computing Core of the NIMH Intramural Research Program. The primary function of this core is to support functional neuroimaging research at the NIH. This includes development of new data analysis techniques, their implementation in the AFNI software, advising researchers on the analysis methods, and instructing them in the use of software tools.

Paul A. Taylor
Core Director for the SSCC

 Paul has been staff scientist in the SSCC since 2015, and has been 
 Core Director since 2023. He works on many ofthe diffusion weighted
 imagings tools in AFNI, as well as on the FMRI and generalprocessing
 ones. He also likes data visualizaton and quality control (QC).

Daniel Glen

  Daniel Glen started in November 2004 as a Computer Engineer.
  Daniel has a BS from Johns Hopkins University in Chemical Engineering. Before coming to
  NIH, his prior work was with the US Navy as electrochemical research scientist where he
  developed and analyzed battery materials. he then worked with a nuclear medicine
  equipment manufacturer as a software engineer. At NIH, he worked in the laboratory
  of Louis Sokoloff on cerebral glucose metabolism and blood flow. His interest
are now mostly on issues related to human and animal atlases and template, spatial alignment and
the development of new visualization methods.

Portia Devenish

 In March 2019, Portia Devenish began working at NIMH as a lab coordinator.
 As a dependable lab administrative specialist, she is skilled in organizing,
 coordinating, multitasking, anticipating needs, interacting with vendors,
 overseeing daily operations across four laboratories, and serving as
 a conduit between the lab and the outside world.  Her favorite quote is,
 "Success isn't about the money you make; it is about the difference
you make in people's lives."

Justin K. Rajendra 

 Justin joined in 2017 after more than a decade of clinical research in various
 neuroscience related fields (depression, post stroke rehabilitation, mindfulness,
 chronic fatigue). Modalities included fMRI, PET, fNIRS, TMS, EMG, EEG,
 motion capture, clinical performance measures. He previously worked at
 Emory University in the department of Psychiatry as a research informatics analyst.

Yamuna Narayana Swamy  

 Yamuna studied medical image analysis and inverse problems in Diffuse optical
 tomography for her graduate studies. Following this she worked as a research
 associate in the astrophysical relativity group at ICTS where she worked on
 parameter estimation in gravitational waves. She joined the AFNI group in
 September 2020 as a postdoc, and currently she is working on implementing
 deep learning methods on MRI image analysis.
