ASYMMETRIC INDUCTION; ENANTIOSELECTIVE CATALYSIS. Expert has developed chiral organometallic compounds for use as asymmetric catalysts. He has studied the synthesis, structures, and applications of chiral metallocene complexes.

INORGANIC CHEMISTRY; COORDINATION CHEMISTRY; ORGANOMETALLIC REACTION MECHANISM. Expert has expertise in inorganic, coordination, and organometallic chemistry as well as in the application of inorganic, coordination, and organometallic compounds in organic synthesis and catalysis. He developed new organometallic-based approaches to the synthesis of heterocyclic compounds, especially pyridines and pyrazines.

TRANSITION ELEMENT CHEMISTRY; TRANSITION ELEMENT COMPOUND. Having expertise in transition element chemistry, Expert has worked with the synthesis, structures, bonding, and chemical reactivity of transition metal compounds, including metal salts, coordination complexes, and organometallic compounds. In particular, he has done extensive work on the chemistry of "early" transition metal complexes containing titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, and tungsten. He is knowledgeable of both fundamental and applied aspects of the chemistry of these transition elements.

TRANSITION ELEMENT CATALYSIS. Expert's work has been primarily devoted to developing new homogeneous catalysts for olefin polymerization, C-H activation, carbonylation, and other reactions. He has expertise in transition element catalyst design, mechanisms of catalytic reactions, and stereoselective catalysis.
