About Me

I am a geoscience professional with expertise in erosion and sediment control, stormwater pollution prevention, and Phase I/II environmental site investigations. With a Ph.D. in Applied Geology (Environmental Mineralogy and Geochemistry) from Kent State University, Ohio, I bring a strong analytical background to environmental challenges.

I have completed the 40-hour HAZWOPER training and a 4-hour Erosion and Sediment Control course, demonstrating my commitment to environmental safety and regulatory compliance. My technical skills include data analytics and Python programming, allowing me to bring modern analytical approaches to geoscience problems.

Areas of Expertise

Environmental Site Assessment
Stormwater Management
Erosion Control
Geochemical Analysis
Data Analytics
Python Programming
HAZWOPER Certified
Environmental Compliance

Stormwater Solutions

Professional stormwater management tools and calculators for environmental engineers and consultants. These tools help ensure compliance with NPDES permit requirements and EPA stormwater regulations.

SWPPP WQv & RRv Calculator

Calculate Water Quality Volume (WQv) and Runoff Reduction Volume (RRv) for stormwater management projects based on site-specific parameters.

Site-Specific Parameters

90th percentile storm depth typically 1.5 in for NYC
Total area of the site used for percent impervious calculation
Total tributary area to the practice. Can include off-site areas
Current total impervious area on site
Impervious area after construction/development
Choose A, B, C, or D to set the specific reduction factor S
