プロフィール概要

I am a PhD astrophysicist and data scientist with 10+ years of experience extracting insights from complex, noisy, high-dimensional datasets. My research has involved developing custom analysis pipelines, statistical models, and image-processing workflows for some of the world's most demanding scientific instruments — including Hubble (HST), JWST, VLT/MUSE, Gemini, and ALMA. I bring the same rigor to commercial projects in data analysis, image processing, scientific Python development, and technical writing. Core technical skills: • Programming: Python (NumPy, SciPy, pandas, astropy, scikit-learn, matplotlib), C, R, MATLAB, Java, SQL • Statistics & modeling: Bayesian inference, MCMC optimization, regression, parametric and non-parametric modeling, uncertainty quantification • Image & signal processing: multi-band photometry, PSF modeling, source extraction, denoising, kinematic and spectroscopic analysis • Data pipelines: large-dataset reduction, automation, reproducible scientific workflows Services I offer: • Data analysis, statistical modeling, and visualization for scientific and commercial datasets • Image and signal processing (astronomy, remote sensing, microscopy, satellite imagery, scientific imaging) • Python scripting, pipeline development, and scientific software consulting • Bayesian/MCMC modeling and uncertainty analysis • Scientific and technical writing, editing, and literature reviews • Grant and proposal support (NSF, NASA, ESA, ERC, Horizon Europe) • Peer review, technical due diligence, and expert consultation for space tech and deep-tech startups • Tutoring and mentoring in physics, astronomy, statistics, and scientific Python Credentials: PhD in Physics (University of Utah), postdoctoral and fellowship positions in the UK, USA, and Germany, and 12+ peer-reviewed publications including a co-authored paper in Nature on the discovery of an intermediate-mass black hole. I have led successful telescope-time proposals on ALMA, Gemini, and VLT/MUSE, and presented at international conferences across Europe, the Americas, and Asia. Please reach out with a brief description of your project — I'd be happy to discuss scope, timeline, and how I can help.
