About us

Mission Statement

The Transport: Modeling, Numerics & Theory Laboratory (TMNT-Lab) strives to combine advanced mathematical concepts and experimental results with physical intuition about the modeling of flowing materials in order to make progress on fundamental questions in mechanics. Specifically, an overarching theme of the TMNT-Lab's research is transport (e.g., as a means of effecting mixing or for mitigating separation). 

A note to prospective students:


For further information on applying to Purdue and admissions to the ME graduate programs click on the respective links. Admissions are only made by the Graduate School at Purdue on the recommendation of the ME Graduate Admissions Committee. The PI does not and cannot admit applications, therefore applications must be sent to the Graduate School and the School of ME at Purdue, no applications should be sent to the TMNT-Lab or the PI.


Due to an extreme amount of email regarding positions and admissions, at this time it is the TMNT-Lab policy that only the most urgent and relevant emails can be answered. Apologies in advances to the rest. For example, general inquires (e.g., "are there positions available?") about graduate studies cannot be answered due to volume. Meanwhile, specific inquiries (e.g., "I have read your 2018 paper in JFM, and I am attempting to use the result in equation (xy) to do [blank], can I ask the following questions ... ?") from those with high academic and research qualifications are welcome and will be answered with priority.
