Evolution of Molecular Resistance to Snake Venom α-Neurotoxins in Vertebrates
We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Electrocatalysis of CO2/CO interconversion and Hydrogen Evolution in Bicarbonate Buffers
Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

environment in tuning electrochemical CO2 reduction reaction and H2 evolution reaction
This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…

The evolution of chemical diversity in plants : pyrrolizidine alkaloids and cytochrome P450s in Jacobaea

Convergent molecular evolution of toxins in the venom of advanced snakes (Colubroidea)
The explosive radiation and diversification of the advanced snakes (superfamily Colubroidea) was associated with changes in all aspects of the shared venom system. Morphological changes included the partitioning of the mixed ancestral glands into two discrete glands devoted for production of venom ormucous…

Essentiality of conserved amino acid residues in β-lactamase
Evolution acts via mutations in amino acid sequences. Substitution of essential amino acids leads to a nonfunctional protein. l.

Population size fails to explain the evolution of complex culture
The logic seems inescapable indeed. The bigger the population, the higher the probability it contains an Einstein. Hence, bigger populations are more likely to develop complex culture.

Evolutionary Developmental Biology of Bitterling Fish
We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

Resolving gas-phase metallicity in galaxies
Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

Distant star formation in the faint radio sky
One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.
