Arvind: physicist
Arvind is a physicist. Arvind’s research involves both computer based analysis, which they conduct largely in their office, and laboratory work.
Arvind’s lab-based work is often split across multiple laboratories, only some of which are university owned, because the use of larger laboratory facilities is competitively awarded and relatively constrained.
On most days, Arvind spends their time at a computer, focusing on tasks such as writing proposals, planning experiments, running simulations, analysing data, and handling administrative duties. Their research relies on advanced computational tools that exceed the capacity of a personal computer, requiring the use of powerful supercomputers. Arvind also develops models and code essential for their research.
In the lab, Arvind uses diverse equipment to validate theoretical predictions and enhance applications of their research in new technologies. Depending on the lab, this equipment may be University-owned, and there are opportunities to share resources with other researchers. Occasionally, Arvind purchases new equipment for specific projects, following the University’s procurement procedures.
To connect with colleagues at the University of York, Arvind attends some in-person meetings but primarily relies on video conferencing.
Arvind travels to research facilities in the UK and abroad to conduct experiments and foster collaboration. Facilities in the UK are typically accessible by train, but Arvind usually carpools with colleagues to optimise time at the facility. For international visits, long-haul flights are often necessary, as institutions are located in Europe, the USA, China, Japan, South Korea, and India.
At least once a year, Arvind participates in a large international conference, which can take place worldwide. While they are mindful of how many conferences to attend, some are essential. Travel for these commitments often involves long-haul flights, and the university covers expenses for hotels and meals during overnight stays.
Arvind's environmental choices and impacts
Energy use in office and labs
A portion of the energy used to heat, light, and power equipment in Arvind’s office and labs contributes to the environmental impact of their research. This includes the energy attributed to their work in both locations.
Energy consumption from equipment
The energy used by equipment makes up a large part of Arvind’s research environmental footprint. Their work relies on various energy-intensive tools. Additionally, some computer tasks are more energy-consuming than typical ones. For example, Arvind's simulation tools depend on supercomputers and large datasets, which require a lot of energy for both operation and cooling. Optimising code for efficiency is an important consideration for reducing environmental impact.
Travel choices and impact
Arvind’s travel decisions for experiments, conferences, and other work commitments affect their overall environmental footprint. For instance, taking a train to a lab in the UK is less carbon-intensive than driving. They can further reduce their carbon impact by carpooling with colleagues when possible. Long flights, hotel stays, and food consumed during international trips significantly contribute to the environmental footprint of Arvind’s research.
Remote energy use
Much of Arvind’s computer work relies on remote servers and datasets, so the energy used for these tasks isn’t included in the energy calculations for their office or lab.
