James J. Hickman is the Founding Director of the NanoScience Technology Center and a Professor of Nanoscience Technology, Chemistry, Biomolecular Science, Biomedical Engineering, Material Science and Electrical Engineering at the University of Central Florida. Previously, he held the position of the Hunter Endowed Chair in the Bioengineering Department at Clemson University. Dr. Hickman has a Ph.D. from the Massachusetts Institute of Technology in Chemistry. For the past thirty years, he has been studying the interaction of biological species with modified surfaces, first in industry and in the latter years in academia. While in industry he established one of the first bioelectronics labs in the country that focused on cell-based sensors and their integration with electronic devices and MEMS devices. He is interested in creating hybrid systems for biosensor and biological computation applications and the creation of functional in vitro systems for human body-on-a-chip applications. He has worked at NSF and DARPA in the area of biological computation. He is also the founder and current Chief Scientist of a biotechnology company, Hesperos, that is focusing on cell-based systems for drug discovery and toxicity. He has 166 publications and 20 book chapters, in addition to 34 issued patents out of 50 total patent applications. He was elected to the Board of Directors of the American Institute for Medical and Biological Engineering (AIMBE) for 2 consecutive terms, the premier society for Biomedical Engineering of which he is a Fellow. He is also a Fellow of the American Vacuum Society (AVS) and National Academy of Inventors (NAI) as well as BioFlorida’s Researcher of the Year (2022). Dr. Hickman along with Dr. Michael Shuler, won the Lush Prize, in the Science Category, which Supports Animal Free Testing in 2015.

One of the primary limitations in drug discovery and toxicology research is the lack of good model systems between the single cell level and animal or human systems. This is especially true for neurodegenerative diseases such as ALS and Alzheimer’s as well as spinal cord injury. In addition, with the banning of animals for toxicology testing in many industries body-on-a-chip systems to replace animals with human mimics is essential for product development and safety testing. Our research focus is on the establishment of functional in vitro systems to address this deficit where we seek to create organs and subsystems to model motor control, muscle function, myelination and cognitive function, as well as cardiac and liver subsystems. The idea is to integrate microsystems fabrication technology and surface modifications with protein and cellular components, for initiating and maintaining self-assembly and growth into biologically, mechanically and electronically interactive functional multi-component systems. Specific embodiments of this technology are the creation of a functional human NMJ system to understand ALS and a long-term potentiation (LTP) for AD utilizing clinically relevant functional readouts. We have investigated four mutations found in ALS patients; SOD1, FUS, TDP43 and C9ORF72. The models have demonstrated variations of the disease phenotype compared to WT for NMJ stability and functional dynamics. We have also demonstrated the LTP model can reproduce ABeta pathology and tauopathy in human cortical neurons and demonstrated how AD therapeutics can recover these effects Examples will be given of some of the other human-on-a-chip systems being developed for CNS and PNS disease applications as well as the results Sanofi has used as efficacy data from one of our models to file the first IND only from MPS data that has enabled a clinical trial (#NCT04658472).
