Kristofor Carlson is a postdoctoral appointee in the Data-driven and Neural Computing group (1462) at Sandia National Laboratories, where he is a researcher in computational neuroscience and neuromorphic engineering. He is currently part of the Hardware Acceleration of Adaptive Neural Algorithms (HAANA) Grand Challenge, a research initiative aimed at developing novel neural based computing algorithms and computing architectures. Kristofor also performs verification and validation on large-scale neural simulations using uncertainty quantification and sensitivity analysis techniques.
Before joining Sandia, Kristofor was a postdoctoral scholar in the department of Cognitive Sciences at the University of California, Irvine. He participated in the DARPA-funded Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE) project where he tested and developed large-scale spiking neural networks (SNNs) for implementation on neuromorphic hardware. Kristofor also extended and maintained an SNN simulator called CARLsim for use on graphics processing units (GPUs). He created a simulation framework that allowed for the parameter optimization of SNNs using evolutionary algorithms and GPUs. Kristofor has a long standing interest in synaptic plasticity and homeostasis at the molecular, cellular, and network levels. He received his B.S. in applied physics and Ph.D. in physics from Purdue University. His thesis work involved the development of biophysically realistic computational models of synaptic plasticity in the hippocampus.
