About us

Mission Statement

The Transport: Modeling, Numerics & Theory Laboratory (TMNT-Lab) combines advanced mathematics with state-of-the-art simulation to model flowing materials (fluids, solids, gases, or anything in between), rationalize experiments, and make progress on fundamental (basic science) problems at the interface of engineering, mathematics, and physics. Specifically, an overarching theme of our research is transport (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 applicants (nor can the PI attempt to sway the admissions committee's decisions, nor will he). 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. Inquiries about the status of an application can be address to the later authorities, the PI cannot comment on such matters.


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?" or "can I join your group?") about graduate studies cannot be answered due to volume. Meanwhile, specific inquiries and technical questions (e.g., "Prof. Christov: 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 most welcome and will be answered with high priority.
