About who we are

Mission Statement

The Transport: Modeling, Numerics & Theory Laboratory (TMNT-Lab) conducts curiosity-driven scientific research at the intersection of engineering, mathematics, and physics. We leverage advanced mathematics with state-of-the-art simulations to study flowing materials (fluids, solids, gases, or anything in between), rationalize experiments, and solve fundamental (basic science) problems. Our aim is to make a lasting impact on the understanding of transport phenomena, as a means of effecting mixing or for mitigating separation, across disciplines.

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. Educational records (transcripts, degree diplomas, etc.) should never be relayed by email because they contain personally identifiable information. Inquiries about the status of an application should be address to the latter authorities, the TMNT-Lab PI cannot comment on such matters.

Due to an extreme amount of unsolicited 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, vague or generic inquires (e.g., "are there positions available?") about graduate studies from those who have not even applied to the graduate programs at Purdue (see preceding paragraph) will not be answered due to volume. Emails that do not follow the rules laid out in the preceding paragraph will be marked as spam and not answered.

To receive a reply, you must make a specific inquiry and/or have thoughtful technical questions (e.g., "Prof. Christov: I have read your 2022 review article in JPCM, 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. Additionally, attempt will be made to address all inquiries from students already enrolled at Purdue (both graduate and undergraduate).

Thank you for your understanding.
