Dr Katherine Giles, the cyclist who was killed as she cycled to work in morning rush-hour traffic in central London on Monday worked at the Centre for Polar Observation and Modelling at UCL.
She gained her degree at UCL in 2000 and PhD in 2005 and is thought to have cycled the same route for years.
The tragedy is the second to strike the Centre at UCL after its director 49-year-old Professor Seymour Laxon died after falling down a flight of stairs in January. Dr Giles was expected to be his successor.
In a statement to colleagues Phil Meredith, Head of Earth Sciences, described the loss as 'outrageous unfairness':
"Coming so soon after the accidental death of Katharine's own closest colleague,Seymour Laxon, we are all left with a sense of the outrageous unfairness.
"Katharine had a bright future ahead of her.
"We greatly admired the bravery and sense of purpose with which she took on the many commitments in CPOM following Seymour's demise, and it was clear that she was ready to provide the next generation of leadership in that field."
