Benjamin K TsaiAfter receiving a BSME degree from Brigham Young University, Benjamin Tsai obtained his graduate degrees from Purdue University in Mechanical Engineering, with research focused on radiation thermometry algorithms and radiative transfer in semitranspaent media. Since 1993, he has worked as a physical scientist at NIST (National Institute of Standards and Technology) with research projects including the spectral irradiance scale, rapid thermal processing of semiconductor devices, heat flux, skin reflectance, UV exposure of reflectance standards, and photometry (measurement assurance program and research for luminous flux of LEDs). He has been active in organizing and participating in short courses taught by the Sensor Science Division, including the Radiation Thermometry Short Course, Spectroradiometry Short Course, Spectrophotometry Short Course, and the Photometry Short Course. In addition, he has co-edited several volumes in the Experimental Methods in the Physical Sciences (EMPS) Series. Read More Read Less
