Rafid is a second year MS student at the Institute for Computational and Mathematical Engineering at Stanford University. His interests lie in tackling social and environmental problems faced in the developing world, particularly in Bangladesh, Southeast Asia, Africa, and South America. Part of his focus is finding creative and innovative ways to apply technology and engineering to connect developed nations such as the United States and many countries in Europe with the developing world. Some of his interests include data analysis of environmental issues related to climate change, agriculture, food insecurity, and greenhouse gas emissions. He is also interested in developing mathematical models mapping the worlds poverty rate, food consumption, population dynamics, and health of those living in poverty.

Comparative Developmental Toxicity of Desalination Brine and Sulfate-Dominated Saltwater in a Euryhaline Fish
ARCHIVES OF ENVIRONMENTAL CONTAMINATION AND TOXICOLOGY
2017; 72 (2): 294-302
Desalination is a promising sustainable solution to meet growing water needs of cities across the United States. However, the environmental impacts of the resulting filtrate (brine) discharged to surface water need to be evaluated before large-scale desalination can be successful in the United States. Developing fish are especially sensitive to changes in salinity and varying ionic composition. Limited research is available on the impacts of hypersalinity on chronic vertebrate embryonic development, particularly on sublethal effects. To investigate this, Japanese medaka (Oryzias latipes) embryos were treated with: (1) graphite filtered freshwater; (2) artificial seawater [17, 35, 42, 56, and 70 parts per thousand (ppt)]; (3) effluent from a desalination facility at Monterey Bay Aquarium, CA, diluted to 75, 50, and 25% with 35 ppt artificial seawater to simulate mixing (39, 42, 46, and 50 ppt); (4) artificial San Joaquin River water (CA, USA) (9, 13, and 17 ppt); and (5) artificial San Joaquin River water diluted to 75, 50, and 25% with artificial seawater to simulate estuarine mixing in the San Francisco Bay (13, 19, 24, and 30 ppt). Percent hatch, survival post hatch, deformities, swim bladder inflation, and median day to hatch were recorded to calculate EC50 (50% effect concentration) and NOEC (no observable effect concentration) values. No significant difference was observed between artificial seawater and Monterey Bay aquarium effluent (EC50 = 45-55 ppt). However, San Joaquin River water decreased survival post hatch and increased deformities in comparison to artificial seawater and San Joaquin River water mixed with seawater, suggesting that unique ion compositions may play a role in embryo and larval toxicity.
