<h2 class="section-title">About Me</h2>
</div>
<!-- Academic Biography -->
<div class="academia-only">
<p style="font-size: 1.15rem; margin-bottom: 1.5rem;">
I am an Associate Investigator at the ARC Centre of Excellence for Gravitational Wave Discovery (<a href="https://www.ozgrav.org/" target="_blank" rel="noopener">OzGrav</a>) and an Adjunct Research Fellow within the Centre for Astrophysics and Supercomputing at <a href="https://www.swinburne.edu.au" target="_blank" rel="noopener">Swinburne University of Technology</a>. I am also a member of the LIGO-Virgo-KAGRA (LVK) Collaboration.
</p>
<p style="color: var(--text-secondary); margin-bottom: 1.5rem;">
My research bridges gravitational-wave observations and theoretical stellar astrophysics. I investigate the formation pathways of merging compact objects—binary black holes, binary neutron stars, and neutron star-black hole systems. By using and co-developing rapid binary population synthesis tools, I model how isolated massive binary systems interact through mass transfer, common-envelope phases, and stellar winds.
</p>
<p style="color: var(--text-secondary);">
Previously, I was awarded an Australian Research Council Discovery Early Career Researcher Award (DECRA) Fellowship to study gravitational-wave progenitors. I completed my PhD in Astrophysics at the University of Birmingham in 2017.
</p>
</div>
<!-- Industry Biography -->
<div class="industry-only">
<p style="font-size: 1.15rem; margin-bottom: 1.5rem;">
I am a Scientific Software Architect with 9+ years of experience engineering complex numerical simulations, statistical data pipelines, and database querying engines for astrophysical data. I am a member of the international LIGO-Virgo-KAGRA Collaboration.
</p>
<p style="color: var(--text-secondary); margin-bottom: 1.5rem;">
I specialize in building and optimizing rapid binary stellar population models (such as `COMPAS`), running massive parallelized simulations on high-performance computing (HPC) clusters, and using Bayesian inference techniques to align model predictions with observational constraints. My daily work involves designing object-oriented simulation code (in C++ and Python), maintaining open-source codebases, and translating statistical formulas into clean, high-performance algorithms.
</p>
<p style="color: var(--text-secondary);">
I hold a PhD in Astrophysics and specialize in quantitative modeling, statistical distributions, data visualization, and open-source software collaboration.
