Dr. Xiaoguang Meng's research is focused on environmental surface chemistry, developments of metal oxide based adsorbents, and development of chemical and physical processes for treatment of arsenic and heavy metals.

He has published 56 papers in peer reviewed scientific journals, obtained four US patents, edited a book, and managed 25 research projects with a total funding of more than $6.5 million.

Dr. Meng is heavily involved in green research initiatives, and in 2002 along with Dr. Christos Christodoulatos and Dr. George P. Korfiatis, developed a patented nanocrystalline titanium dioxide adsorbent and established Hydroglobe, a company dedicated to delivering affordable water purification systems to the global marketplace.

This material has been used in commercial filters for treatment of arsenic, lead and other heavy metals. The high surface activity of these patented nanocrystals strongly binds heavy metals and is also an active photocatalyst. In the presence of dissolved oxygen and UV-light radiation, the highly reactive chemicals formed on the surface of the titanium dioxide destroy organic pollutants and kill bacteria.

He also developed an effective household filtration process and successfully demonstrated it in nearly 700 families in Bangladesh between 1999 and 2005.
