Hey! Glad you’re here!
I’m Xitong Sun, a first-year M.S./Ph.D student in Mechanical Engineering at University of Texas at Austin.
I received my B.E. degree in Microelectronics Science and Engineering in July 2025 at Southern University of Science and Technology (SUSTech), a young university established in 2010 in Shenzhen, China (a short story about SUSTech). During my undergraduate studies, I conducted research on MEMS-based gas sensors under the supervision of Prof. Fei Wang.
In August 2025, I was proud to join the University of Texas at Austin as a member of the longhorns and begin my M.S./Ph.D studies in Mechanical Engineering. Since then, I have explored a range of research areas, and my current interests focus on advanced modeling and control techniques for high-performance power electronics, as well as emerging power electronics based on piezoelectric passive components.
I have experience in IC-level design and simulation (e.g., Cadence Virtuoso), system-level design and prototyping (e.g., KiCad, PLECS, Code Composer Studio (CCS)), as well as cleanroom-based device fabrication.
Looking ahead, I plan to re-apply to PhD programs in Fall 2027, with a focus on Power Electronics!

📝 Research and Publications
Advised by Prof. Fei Wang
- This work, for the first time, realized the patterning of different gas-sensing materials through multiple photolithography steps, and combined the sensor array with a support vector machine (SVM) algorithm to accurately identify different gases and concentrations.

Design and Fabrication of LN-Based Piezoelectric Isolation Transformers
Advised by Prof. Ruochen Lu
- This ongoing project focuses on the design, modeling, and microfabrication of lithium niobate (LN)-based piezoelectric isolation transformers for emerging power electronics applications.
- Different LN and isolation-layer thicknesses are studied to evaluate their effects on electrical isolation and acoustic coupling.
- The work aims to explore piezoelectric isolated transformer structures as potential alternatives to conventional magnetic components in compact and high-performance power conversion systems.

Advanced Modeling and Control Techniques for Multiphase Buck-Type Power Converters
Advised by Prof. Yicheng Zhu
- This ongoing project focuses on advanced modeling, simulation, and control techniques for multiphase buck-type power converters. The work includes literature review, simulation-based verification, and comparative analysis of different control methods in terms of stability, transient performance, complexity, reliability, and practical implementation considerations.

😎 Play Hard
I graduated from Southern University of Science and Technology in 2025. I am deeply grateful to all the teachers, friends and family members who supported me along the way. SUSTech gave me countless precious memories, I will keep these precious memories in my heart forever.
In my free time, I enjoy playing basketball. I proudly support the Houston Rockets and the Texas Longhorns. My favorite player is Kevin Durant — graduated from UT and now play for Houston Rockets.
I’m also a big fan of classical music. I spent four joyful years with the SUSTech Philharmonic, and one year as orchestra president. I participated in more than 20 performances. I also enjoy attending concerts and have heard performances by the San Francisco Symphony Orchestra, New York Philharmonic, and National Symphony Orchestra. My favorite piece is Sibelius’s Violin Concerto in D minor.
I also love traveling and exploring different landscapes. Yosemite is my favorite national park.
