During my Ph.D.study at the University of North Carolina,I was a Research Assistant supported by the NSF award'Collaborations in Mathematical Geosciences(CMG)'.My thesis on passive scalar intermittency under the guidance of Professor Richard McLaughlin and Professor Roberto Camassa focused on identifying the physics responsible for the non-Gaussian statistics observed for many physical quantities in experimental and natural turbulence.I also worked in the UNC Fluids Lab and analyzed data on underwater turbulent plumes and jets whose behavior may have great environmental impacts. After my graduation,I started my postdoctoral research at the University of Michigan funded through the NSF award'Studies in Mathematical Physics(PHY)'.With the help of my faculty mentor,Professor Charles Doering,I integrated my expertise in asymptotic,variational and stochastic methods and reconciled previously conflicting results on flow-enhanced scalar diffusion by addressing the different physical mechanisms and mathematical challenges.Since I became a Postdoctoral Fellow for the IMA Thematic Year on Complex Fluids and Complex Flows,I have extended my work seeking to optimize industrial and microfluidic mixing.Additionally,I started to explore the biological applications of my knowledge with research projects in biogenic mixing.Furthermore,I have been consistently inspired by interacting with physicists,environmental scientists and engineers through various conferences and workshops,including the notable Geophysical Fluid Dynamics Summer Program at the Woods Hole Oceanographic Institution that has beening going on for more than half a century now. A list of my publications and talks can be found in my CV HERE.And the details of my projects can be found HERE. 相关链接浙江大学本科招生网浙江大学竺可桢学院浙江大学数学科学学院中国数学会中国工业与应用数学学会
