Madhusudhan Kodam is an associate research scientist in the Solids Processing Group, Core R&D at the Dow Chemical Co. in Midland MI (Email: mkodam@dow.com). He has been with Dow for more than five years. He is involved in solving a wide variety of problems related to particle technology, ranging from caking and flowability of bulk solids to pneumatic conveying, fluidization, and other two-phase flow problems. He received his PhD in mechanical engineering from Purdue Univ., where he developed novel contact-detection algorithms for true pharmaceutical tablet shapes and different attrition mechanisms as part of his PhD studies. His research interests include continuum modeling of bulk solid flows and the application of fundamentals for solving bulk solid flow problems.
