Dean Dawson
Vice President, Marketing and Business Development
Dean has a passion for marketing and business development of high technology products. His experience spans different stages in market adoption ranging from pioneering and scaling new technologies like the photothermal AFM-IR in startups like Anasys to growing the market share of products in established market leaders like Bruker. At Anasys, Dean was the VP for Marketing and he helped the founding team to establish the photothermal AFM-IR as the leading technology for nanoscale IR spectroscopy leading to widespread adoption in leading academic and industrial institutions. When this market success led to the acquisition of Anasys by market leader Bruker, Dean joined Bruker as the Senior Director and Business Unit manager, nanoIR Spectroscopy Products. At Bruker, Dean was responsible for effectively integrating the nanoIR within Bruker’s engineering and manufacturing organizations. He was instrumental in the creation of the ICON-IR product that integrated the nanoIR into Bruker’s flagship and market leading ICON AFM platform and which has the promise to disrupt the high end AFM market. Dean has held other roles at Bruker including Senior Director of Product Management for Bruker’s research AFM division. Dean also worked for Veeco Instruments as the Senior Director of Product Management, overseeing the development and growth of Automated AFM for industrial markets. Dean has a BS in Applied Physics from De Montfort University, UK and Master’s in Engineering Management from Coventry University, UK.

Craig Prater
Chief Technology Officer
Dr. Craig Prater is CTO and co-founder of PSC and previously served as CTO for Anasys from 2007-2018, until the acquisition of Anasys by Bruker and the founding of PSC. Previously Craig served as a visionary leader in atomic force microscopy research, technology, and product development at Digital Instruments/Veeco (now Bruker). Craig was recognized in 2005 as the first Technology Fellow at Veeco, the highest technical rank in the organization. Craig has co-authored more than 140 scientific and trade publications and patents with more than 10,000 citations. Craig has also been PI on several successful research projects with DOE, NSF, and NIST. Craig has performed photothermal spectroscopy research since 2007 and has led O-PTIR technology development since 2017 and was recognized with the 2023 Williams-Wright Award for “significant contributions to vibrational spectroscopy while working in industry.” Craig has a PhD in Physics from the University of California, Santa Barbara.

Roshan Shetty
Before co-founding Photothermal Spectroscopy Corp., Roshan Shetty served as co-founder and CEO for Anasys Instruments. Anasys pioneered the field of nanoscale IR Spectroscopy, via photothermal IR (PTIR) technology that uses an AFM probe as the IR absorbance detector. The AFM-PTIR technique was widely adopted by leading academic and industrial researchers. Anasys was acquired by Bruker in April, 2018. Prior to Anasys, he was the Director of Strategic Alliances for Veeco Instruments, where he laid the foundation for the widely successful Quantitative nano-mechanics (QNM) product platform at Veeco/Bruker Nano. The QNM platform revolutionized the field of nano-mechanics and contributed to over $100 Million in cumulative revenues. He conceived of and executed the $13.2 Million Strategic Alliance with Dow Chemical in nano-mechanical characterization that won a $6.6 Million NIST ATP award from a field of 800 corporate applicants. In a former life on another galaxy, Roshan was the co-founder/COO of, a click/mortar wedding registry based in Paris, Milan and Munich that raised over $20Mill and employed over 100 people with strategic online/offline partnership with Galeries Lafayette. He was a former Investment Banker at Alex Brown, San Francisco and Operations Manager at KLA Tencor, San Jose. He has an MBA from INSEAD, a Masters in Optical Sciences from the University of Arizona and a BS in Electrical Engineering from BITS, Pilani.
