Kevin Kjoller
Vice President
Kevin is regarded within the SPM industry as one of the world’s leading technology and applications experts on the Scanning Probe Microscope. Kevin has been involved with the research and development of SPMs since 1987, mostly within Digital Instruments, and then later Veeco Metrology. At different points through his 16 year career with DI/Veeco, he managed all of the applications and research for SPM product development. Kevin currently serves as Vice President at Photothermal Spectroscopy Corp., and still works for Anasys Instruments, where he has been responsible for the development of the award-winning nano thermal analysis technology and VESTA systems, as well as pioneering applications for Anasys’ patented nanoIR spectroscopy. He has a BS in Physics from the University of California, Santa Barbara.
Craig Prater
Chief Technology Officer
Craig was the Chief Technologist for Veeco Metrology, responsible for new technology and intellectual property. In his 15 years at Digital Instruments and Veeco Metrology, Craig has served as a visionary leader in research, product engineering and technology development in the field of atomic force microscopy. He led the development of automated AFMs which enabled widespread use in semiconductor and data storage fabrication facilities. Craig was recognized in 2005 as the first Technology Fellow at Veeco Instruments, the highest technical rank in the organization. During his career at Anasys Instruments, Craig authored multiple patents for nanoscale IR spectroscopy technologies. Craig is now serving as CTO of Photothermal Spectroscopy Corp., helping further the Photothermal Infrared Spectroscopy technique he helped develop. In addition to technical responsibilities, he managed an IP portfolio of over 100 patents. Craig has over a dozen issued patents and more than 50 scientific publications with a total of more than 5000 citations. Craig has a PhD in Physics from UC 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, he conceived of and executed the $13.2 Million Strategic Alliance with Dow Chemical in nano-mechanical characterization that won a $6.6 Million ATP award from a field of 800 applicants and laid the foundation for the widely successful QNM (Quantitative nano-mechanics) product platform at Veeco/Bruker Nano. 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.
