No IDW this year because it was held in August as part of the silicon conference. Martin travels to Taka Kohzuma's lab for a week to finish writing papers from the June experiments (Ibaraki University in Mito, Japan). A quick visit as the teaching term continues.
October, 2011
A quiet month as classes continue. Janice Lee, another old-group member, who isn't - came and visited the lab on the eve of Western's Homecoming. The Thanksgiving Weekend was beautifully warm - photos to come- in Parry Sound.
Martin will give a talk "If grass is green, why isn't blood green?" as part of "The International Year of Chemistry during National Chemistry week" in Philadelphia at Drexel University.

Joining our group for graduate studies, summer research or for your 4th year project
If you are interested in joining the Stillman Bioinorganic Group for graduate school have a look here for more information about submitting an application. Research in our group offers a wide range of stimulating experiences at the boundary between inorganic chemistry and biology. Metals control life!
Joining the Stillman Bioinorganic Research group, continued..... Join us for Graduate Work
The Stillman lab has one of everything we need - complete recombinant protein production facility; new spectrometers - optical (UV-visible, CD, MCD, emission, atomic absorption) and just this year a brand news Bruker micrOTOF II ESI-MS instrument; excited state lifetime capabilities; low temperature measurement capabilities; electrochemistry and photochemistry facilities; access to as much computation as you want both in the lab in through our accounts on Sharcnet; a wonderful group of staff members helping us work. We collaborate with groups around the world with everybody in the lab travelling outside Canada most years to work in our lab or attend a conference - visits from both our collaborators and their students are frequent. In other words: please consider us for your graduate work. Oh yes, we are considered to be the happiest chemistry department in the country. We are.
Current research topics available for new students: Studies of the metal binding kinetics in metallothioneins using optical, mass, and stopped flow techniques (see our papers on As(III)); studies of heme transport proteins; studies of the electronic structures of nonsymmetric porphyrins and corroles using MCD and theoretical methods.
Summer 2012 projects are available; a new instrument is installed; Fall is really here. We welcome enquiries for summer 2012 projects from high achieving students in the ICE and MITAC-global programmes.
The Stillman lab offers a large number of exciting summer-long research projects for 2011 in bioninorganic chemistry. Western is a great university to come to - living here is really pleasant in the summer and costs are low. We will train you to use our new state-of-the-art instrumentation and theoretical methods. Current on-going projects involve characterization of novel porphyrins, studies of metallation to metallothioneins, studies of metal exchange between proteins, and studies of the heme-binding proteins in bacteria. We have projects available from metal binding to a range of proteins using ESI-mass spectrometry to porphyrin spectroscopy coupled to theoretical calculations. Please contact Prof. Stillman for more example (martin.stillman@uwo.ca). We look forward to hearing from you.
