目前课题组主要开展四个方向的研究，分别是：
. V5 G# @' Q% L/ m （一）、陆源有机物及其沉积记录：以木质素、正构烷烃、脂质等为特征生物标志物，研究其在海洋中的沉积记录及其环境地球化学意义。 0 g' D6 b. }& [
（二）、现代有机污染物及其转化机理：通过实验室模拟实验中降解中间产物或/和代谢产物的分析、稳定同位素分馏效应的测定以及理论计算，与现场测定结果相结合，研究典型有机污染物在环境中的来源、分布及其光降解和生物降解机理，结合定量构效关系研究，评价其生态风险。目前已经开展的污染物研究包括多环芳烃（PAH）、多氯联苯（PCB）、多溴联苯醚（PBDE）、德克隆（DP）、塑化剂（PAES）、烷基酚（NP和OP）、微塑料（MP）等。
# F8 g" u) Z+ _( j& O0 Y （三）：海洋资源化学：通过分析海洋来源物质的成分、结构，确定其可能的生物能量来源，判别其使用价值，尤其是潜在价值。通过各种化学方法或手段转化为可持续资源、能源，如浒苔液化、镁盐晶须、人工海水等。针对当前环境氮、硫污染问题，从源头出发，开展气体、液体的除氮、脱硫工艺研究。
" a6 r" W/ v8 y- e （四）、微生物化学：通过分析海洋来源微生物群落结构、功能基因、次级代谢产物以及中间产物来探索小分子活性物质的生物合成途径、机理，进一步确定元素迁移路径和能量的转化方式，同时探索发现活性天然产物。通过特殊环境来源微生物的驯化，探索微生物在污染物的去除、降解方面的应用。 / P0 i; W( y4 I A7 K& W
