  1. Personal Statement 

I have been conducting research in the field of nanotechnology and point-of-care diagnostics since I started research activities in the University of Cincinnati as a PhD student in 2004. Over the last 16 years, I have worked in several areas applying multi-functional nanofiber membranes, which led to multiple breakthrough findings and outcomes. My novel approaches as well as research conclusions have been internationally cited and utilized to develop variants in various applications and to understand the fundamental science. Currently, I am working as a Senior Research Associate and Adjust Instructor at the University of Cincinnati, serving as a highly motivated multidisciplinary research engineer with outstanding laboratory skills and methodical approaches, leading to high impact outcomes and awards upon synergistic collaborations with various institutes such as the Johns Hopkins Hospital, University of Health Sciences and Pharmacy in St. Louis, P&G, UC medical and other UC departments.


My application-oriented research is mainly focused on two categories: development of electrospun nanofiber applications and paper-based point-of-care diagnostic devices. Many articles in high impact journals ~ 42 articles (mostly ranked in top 10% in the field), 22 oral presentations, 30 poster presentations, and 2 US patents have been made upon my successful research outcomes. As a post-doctoral fellow, a competitive-based research fund award was granted to me in 2011 and the proposed project was implemented successfully by publishing a high impact article in ACS Applied Materials and Interfaces, cited 133 times since 2013 based on Google Scholar.


Current research activities are mainly focused on development of multi-axially electrospun nanofiber applications such as (1) “on-demand” programmable drug delivery system for wound dressing and localized cocktail chemotherapy, (2) non-hormonal contraceptive nanofibers, (3) mobile electrospinning system for dura repair, and (4) membrane-based microfluidic devices for point-of-care diagnostics.

  1. Contributions to Science

I have been recognized in the electrospinning research area as one of leading researcher, especially in coaxial electrospinning research. Using coaxial electrospinning, I have first demonstrated the superhydrophobic and oleophobic membranes by fabricating Teflon coated nanofibers in one step, which was the first to demonstrate coaxial fibers with non-electrospinnable polymer solution in sheath. This breakthrough journal article has been cited ~ 315 times as of October 2019. Similar strategy has been utilized with non-electrospinnable enzyme in sheath to protect soldiers from anti-warfare agent in the battlefield. Another breakthrough in the field has been accomplished by demonstrating the dual drug release from tri-layered coaxial nanofiber membranes. Combining the burst release and the controlled release into a single delivery system leads a synergistic effect and opens the door to many biomedical applications including cancer therapy, wound dressing and tissue engineering. In 2017, I have demonstrated the “on-demand” drug release from nanofiber membranes triggered by external stimuli such as pH values, which potentially beneficial for cancer researches, receiving many citations in the field. Currently, we are collaborating with the world-renowned medical team in the Johns Hopkins University to develop the novel local cancer therapy for deadly brain cancers and our promising results was published in Nature Scientific Report in 2019. I also published the comprehensive review article about coaxial electrospinning, which was selected as Very Important Paper and Cover feature. My research outcomes have been cited ~ 1060 times as of May 2020. Related publications are listed below.
