Hanliang Guo

Welcome

My new site is available here.

I am broadly interested in the fields of biological fluid mechanics and active matter.

I develop reduced-order models and fast numerical algorithms for low Reynolds number fluid problems related to biology and human health.

I am also passionate about teaching applied math and engineering courses.

I have been working as a Postdoctoral Assistant Professor in the math department at the University of Michigan, Ann Arbor since September 2018, working with Professor Shravan Veerapaneni. I obtained my PhD in Mechanical Engineering at the University of Southern California (USC) in 2017, advised by Professor Eva Kanso.

You are welcome to check out my CV, google scholar, and research gate profiles.

Software

Xlip

This Matlab App solves the optimal slip profile of axisymmetric microswimmers with user-defined shape. Such a slip profile minimizes the power loss of the active microswimmer swimming at unit speed. The algorithm is documented in the paper "Optimal slip velocities of micro-swimmers with arbitrary axisymmetric shapes" (https://doi.org/10.1017/jfm.2020.969).

Matlab users: The app can be directly installed into your Matlab App library. Download the installation file at Mathworks File Exchange.

No Matlab, no sweat: The app can be downloaded and installed as a stand-alone app. The installation file will download the Matlab runtime automatically. [stand-alone apps]

Mentorships

I have been fortunate enough to mentor many talented junior graduate and undergraduate students.

I am currently co-mentoring (with Yabin Zhang) an undergraduate research team (Akash Narayanan, Xiuru Ruan, and Zhuoyu Zhu) investigating different numerical interpolation schemes.

In the Fall 2021 semester, I mentored a group of four passionate undergraduate students (Jenny Jin, Nicole Surgent, Wanting Huang, and Xinyue Qie). They worked on leveraging machine learning techniques to classify microswimmer types (pusher, puller, neutral). The results are summarized in this paper currently under consideration for SIURO.

In the Winter 2021 semester, a group of three awesome undergraduate students at Michigan (Lisbon Wu, Rahmy Salman, and Bohan Xu) worked on the research project "Flow in Confined Geometry". They published their results (and codes) in this website. The Matlab App is available in Matlab Central. Check it out!
