Applying to PhD programs · Fall 2027

Muhammad Raffay Chaudhry
listening to the solid Earth.

Geoscience senior at the University of Wisconsin–Green Bay. I study how fluids and stress move through rock and ice, using seismic signals and geophysical surveys to see what happens underground.

01 — About

Fluids, rock, and ice under stress.

I'm from Pakistan and came to Wisconsin to study geoscience, first at St. Norbert College and then at UW–Green Bay. I've been drawn to the questions you can't see directly: what water is doing inside rock, how a slope weakens before it fails, how a reservoir responds when CO₂ is pushed into it.

I taught myself Python and began building my own tools for seismic data, from waveform processing in ObsPy and SAC to a pipeline that detects P-wave arrivals automatically. This summer I completed the 12-week NSF–EarthScope Seismology Skill Building Workshop. As a research assistant on four projects, I've run electromagnetic surveys, measured fluid inclusions from an ore deposit, and sampled soils and water across Wisconsin.

For my PhD I want to work where fluid flow meets rock and ice mechanics, whether that means monitoring induced seismicity at a carbon storage site, detecting landslides from seismic signals, or understanding how meltwater changes the way an ice sheet moves.

Subsurface

Carbon storage

Geomechanics and monitoring of CO₂ injection: pressure, fluid migration, and induced seismicity.

Hazards

Seismic monitoring

Detecting earthquakes, landslides, and other mass movements in continuous seismic records.

Cryosphere

Ice sheet dynamics

Basal hydrology, glacial seismicity, and models of how ice flows and fractures.

Projects

2026Independent project

Seismic signal processing & P-wave detection

A Python and ObsPy pipeline that pulls waveform data from FDSN web services and applies STA/LTA triggers to detect P-wave arrivals automatically.

  • Python
  • ObsPy
  • STA/LTA
  • FDSN
Methods & validation
Data
Waveforms retrieved programmatically through FDSN web services.
Method
Bandpass filtering followed by a short-term / long-term average (STA/LTA) trigger to flag the onset of the P-wave.
Validation
Tested on a real earthquake recorded at station COP (Copenhagen, Denmark) on 19 February 2009, bandpass filtered 0.5–8 Hz to isolate the arrival from background noise.

EM-31 survey for municipal water-main leak detection

Electromagnetic surveys mapping subsurface conductivity around a suspected municipal water-main leak, turned into GIS conductivity maps and anomaly models.

  • EM-31
  • ArcGIS Pro
  • Gridding
  • Anomaly mapping
Methods & results
Problem
A suspected leak near a municipal water main, with utility records that disagreed on where the main actually ran.
Method
EM-31 terrain conductivity surveys over the site, gridded into high-resolution GIS conductivity maps and spatial anomaly models.
Result
The conductivity anomalies resolved the conflicting utility records of the main's location.
Output
Presented at the AIPG National Conference, Duluth, MN (2026). Awarded Best Poster Presentation.
Dec 2025 – Jul 2026Fluid inclusion RA · Dr. John Luczaj

Ore-forming fluids at Eagle Mine, Michigan

Fluid inclusion microthermometry to characterize the fluids that formed the ore at Eagle Mine and how their temperature changed through time.

  • Microthermometry
  • Thin sections
  • Petrography
  • Fluid–rock interaction
Methods
Samples
Thin sections prepared from Eagle Mine material.
Method
Petrographic observation of inclusion assemblages combined with heating and freezing measurements.
Goal
Constrain the temperature evolution of the mineralizing fluids.
Nov 2025 – Aug 2026Soils RA · Dr. Kevin Fermanich, CSET

Baseline soils for an agrivoltaic conversion

Soil characterization of farmland being converted to solar, establishing a baseline before the panels go in.

  • Soil coring
  • Flash 2000 CHNS
  • GIS
  • Power analysis
Methods
Field & lab
Soil sampling, bulk density, and C/N concentration analysis on a Flash 2000 elemental analyzer.
Analysis
GIS spatial analysis across the study plots to evaluate site suitability and map nutrient distribution. Independently ran a power analysis to test whether the sampling design had an adequate sample size.
Water
Worked with a graduate researcher on water sampling to quantify metal concentrations.
Output
Poster at the UWGB Academic Excellence Symposium (2026).
Nov 2025 – Mar 2026Hydrology RA · Dr. Matthew Dougherty
