Lalit Aggarwal's Email & Phone

Dr. Aggarwal's interest in gem grading arose from his pioneering work in the field of ImageStatistics, a powerful new statistical technique he developed to address problems with large numbers of variables in the early 1980s. He founded ImaGem in 1998 to commercialize the application of ImageStatistics to the gem industry. Using ImageStatistics, Dr. Aggarwal bridged the gap between machine and human grading. Along the way, he developed an integrated technology to collect the image data, the programs to analyze it, and the hardware to handle gemstones and move them through the grading process automatically. Dr. Aggarwal is a successful entrepreneur. A retired university professor, he earned a doctorate in Peace Science from the University of Pennsylvania and has earned three Masters degrees. Dr. Aggarwal has published in such journals as Educational and Psychological Measurement, Communications in Statistics, Quality and Quantity and the Journal of Statistical Computation and Simulation.
