Ricardo Toledo-Crow, Ph.D.

  • Director, Next Generation Environmental Sensor Lab (NGENS)
  • Research Associate Professor, Environmental Sciences Initiative

Dr. Ricardo Toledo-Crow is a native of Mexico City, where he received his degree in Physics at the National Autonomous University. After two years in Europe working at a bio-imaging company for the National University, he moved to the U.S. for graduate studies. He received his Ph.D. in imaging science and optics at The Rochester Institute of Technology with a dissertation on Near Field Microscopy. Since then, he has been in both industry and academia making clinical and analytical instruments and imaging sensors. He worked for Thermo Electron (now Thermo Fisher Scientific) in Middleton WI, and at Memorial Sloan Kettering Cancer Center (MSKCC) in New York City, where he established the Research Engineering Lab. As director of this engineering facility he collaborated extensively with the research and clinical faculty of MSKCC, Cornell Medical and The Rockefeller University. In 2011 he developed the core technology for ColdSteel Laser Inc. a medical device startup which he co-founded with surgeons from MSK. He lives in Hudson Heights with his wife and two young boys and is an avid musicophile with broad-spectrum tastes.
