Biophysicist (Plant Systems)

MEDIUM DemandLOW AI RiskGROWING in SL· Rs.145k+ /mo

About This Role

Studying the physical and chemical mechanisms of plant growth, such as photosynthesis and nutrient transport.

A Day in the Life

Biophysicists specialising in Plant Systems study the physical basis of plant growth, photosynthesis, water transport, and stress responses — applying physics and quantitative methods to improve crop performance and understand plant biology.

  • Measure photosynthetic efficiency using fluorometry and gas exchange systems
  • Study water relations in plant tissues using pressure chambers and pressure probes
  • Model turgor pressure, cell wall mechanics, and plant hydraulics mathematically
  • Conduct confocal or light-sheet microscopy of plant cell dynamics and organelle movement
  • Analyse plant electrical signalling and ion transport with electrophysiology methods
  • Collaborate with plant biologists and agronomists on crop physiology projects
  • Write research papers on plant biophysics findings and present at conferences
  • Contribute to understanding of plant adaptation to drought and heat stress
