Technical Consulting

The Lens Between Data and Insight

The Insight is Yours.

Statistical modeling, machine learning, web development, and custom data visualization. I turn complex data into tools, insights, and systems that work.

Live visualization: Log-Gaussian Cox Process

Services

From statistical modeling to interactive web tools, I bring rigorous methodology and clean engineering to every project.

Why OZ Labs

I combine academic rigor with practical engineering. My work is grounded in deep technical expertise and a track record of building systems that matter.

  • Ph.D.-Level Rigor Statistical and ML methods grounded in solid theory, not black-box heuristics
  • Published Track Record Research published in Nature, Nature Medicine, NEJM, and The Lancet
  • Full-Stack Capability From statistical modeling to production web applications and interactive visualizations
  • Clear Communication Complex results translated into tools and insights you can actually use

# Spatio-Temporal Gaussian Process
# Squared Exponential Kernel

kernel <- function(x1, x2, l, sigma) {
  d <- sqrt(sum((x1 - x2)^2))
  sigma^2 * exp(-d^2 / (2 * l^2))
}

# Build covariance matrix
K <- outer(locations, locations,
           Vectorize(kernel),
           l = 0.5, sigma = 1.0)

# Sample from GP prior
f <- mvrnorm(n = 1,
             mu = rep(0, n),
             Sigma = K)
