Earlier work of his involved the invention (with Aneesur Rahman ) of the microcanonical ensemble approach to lattice gauge theory, which significantly increased computational efficiency in the numerical simulation of quantum field theories. Other work showed that quantum triviality provided new constraints on the Higgs boson , such as a bounded or predictable Higgs mass. Professor Callaway later published a well-cited monograph on the subject. He has also shown a direct connection between black hole entropy and liquid surface tension. He also reformulated the Laughlin model of the fractional statistics quantum Hall effect using random matrix theory, affording a connection to geometric models of string theory, and showed that the superconducting intermediate state allowed a direct view of a quantum phase space.
In his copious free time, he sails the world and climbs its mountains. ( Mount Everest can be seen in the background).
What I looked like (3 weeks without a bath) after climbing McKinley/Denali (Alaska) and HERE. Here I am at the summit And here I am halfway up, at Genet Basin. And here I am climbing the headwall above it, and And here I am finally coming home!
Me and Stuart McGuinness at Kilimanjaro summit (Tanzania/Kenya, Africa) HERE and HERE Crossing into the arctic circle on Baffin Island ( Pangnirtung fjord, Nunavut) with Iain Nicholl and Stuart HERE and HERE
Gathering intrepidness before another Baffin stream
Behind is Mt Thor , a 4101 foot granite cliff with a 105 degree overhang, making it the Earth's greatest purely vertical drop. An interesting climb.
Been there, done THAT ( Aiguille de Rochefort , Alps) and THAT (north face, Tour Ronde, Chamonix, France) and THAT ( Aconcagua, Argentina/Chile). HERE I am at the summit. And HERE I am halfway up. At the summit of the Matterhorn (Switzerland/Italy) HERE. At the summit of the Eiger (Switzerland) HERE. And then there is THAT ( Mt Cook , New Zealand).
Sometimes, for relaxation, I go rock climbing in the Gunks. ( This is called Belly Roll). Some assorted Alpine climbs HERE and HERE and HERE. The Vallee Blanche, ( Mont Blanc , Chamonix, France) moments before I skiied it. Eating a soggy breakfast after a rainy night on Baffin Island. Danger! do not approach! . Climbing Everest with Brian Blessed and Pasang Sherpa is shown HERE . Me at Everest base (Nepal) HERE and HERE .
Returning from another Himalayan expedition HERE . ( Lukla photo by my late friend Ginette Harrison.) Avalanche above Camp 1 on Broad Peak (Pakistan) (good thing I was slow on the way down) HERE . Making basecamp for Broad Peak on the Concordia Glacier is shown HERE . At the summit of Mt Cook (New Zealand) HERE and HERE and my friend Arthur Collins there (photo by me!) HERE . Maintaining proper fluid balance is ESSENTIAL at high altitude. HERE I demonstrate how to do it in Dingboche, Khumbu region of Nepal. Climbing the Khumbu icefall on Everest HERE and HERE . At K2 Base Camp HERE . Note the neat Chamonix bag! At the Khyber Pass (Afghanistan/Pakistan) HERE and HERE . At the summit of Mount Kosciuszko, the highest point of Australia HERE and HERE .

and author time HERE Sometimes I wear very nice clothes like HERE but mostly I am in my shambolic redoubt(i.e.,office) HERE unless I am giving a commencement address at Rockefeller like HERE or riding my horse through Brooklyn. Our lab meetings are somewhat unusual.
Me as a fresh PhD in Seattle HERE
My Erdos number is three, ( John R. Klauder, Jonathan Schaer, Paul Erdos)
as is my Einstein number ( John R. Klauder, Valentine Bargmann, Albert Einstein)
An article I wrote during my four years reporting for a great newspaper.
A good link for people who do not appreciate Biological Physics .
Bloop! Bloop!. Typical med school salaries, long ago, when profs were POOR!.
