In 2011, Wei participated in her first primary research project, directed by associate Professor Jun Shen, using cellulose derivative to separate chiral pharmaceuticals. This project was supported by her undergraduate school, Harbin Engineering University.
In 2012, Wei researched membrane fouling in forward osmosis process for her undergraduate thesis under the guidance of Professor Jun Ma. That was the first time she learned the basic theory of FO, especially the fouling behavior of humic acid, BSA and sodium alginate on the surface of CTA membrane in both PRO and FO modes. This thesis was named as the outstanding thesis by her undergraduate college.
From 2013 to 2014, with the guidance of Prof. Ma and Dr. Zhenghui Wang, some interesting work was completed in Wei’s master’s project. They obtained some uniform and honeycomb-like pores on polymer films by the addition of nonvolatile organic molecules.
From the fall of 2015 to 2016, Wei focused her study on FO. Some behaviors of ion bidirectional transport behavior in FO process were investigated, and Dr. Xinglin Lu gave Wei much help and guidance.
To further understand the mass transport mechanisms in membrane filtration processes, Wei came to Prof. Menachem Elimelech’s group. Her research will focus on membrane fabrication and modification.
