Marine Paleontologist · Data Scientist

Hi. I'm

Dr. Jood
Al Aswad.

The ocean's past is a warning we haven't finished reading.

Earth's oceans have faced catastrophe before. I'm a quantitative paleobiologist tracking how environmental change reshapes ocean life and biodiversity across space and time. My work is inherently interdisciplinary: I blend physiology, geology, oceanography, and data science to understand the tipping points between extinction and endurance.

To my knowledge, I am the first female Saudi paleontologist. One of my goals is student outreach within paleontology, so that everyone feels like they belong!

I also draw digitally and with charcoal, and I'm writing a high fantasy novel woven through with biology and geology. I build fantasy worlds out of the same material I study: deep time, ocean life, and what survives!

The Researcher

Scientist, data thinker,
storyteller.

Who is Dr. Jood?

Warming, acidification, and oxygen loss are dismantling ocean ecosystems faster than we can understand them. The fossil record has seen this before. I draw on biology, geology, oceanography, and quantitative data science to understand how life survived past crises by rifling through roughly 541 million years of history recorded in stone.

For my postdoc, I use statistical modeling alongside Late Pleistocene and Holocene fossils to reconstruct what ocean communities looked like before humans started degrading them by building a data-driven baseline for understanding extinction drivers.

Many marine ecosystems were already unrecognizable by the time modern ecology arrived to study them. The fossil record is how we recover that baseline.

Why this work matters

To save our reefs, we need to know
what we're losing.

You can't measure what we're losing without knowing what was there before. The fossil record is that baseline.

How I work

Interdisciplinary by design.
Data-driven at every scale.

Answering deep-time questions requires pulling from biology, geology, oceanography, and computational science, all at once.

01

Quantitative & Biogeographic Analysis

I use biogeographic similarity measures like Jaccard and construct equal-area hexagonal grids to track how global marine community composition has changed through time. Combined with large fossil occurrence databases, this lets me pull community-level and biogeographic signals from deep time and turn them into statistically tractable narratives about survival, diversity, and collapse.

02

Cross-Disciplinary Integration

Fusing paleontology with marine biology, physical oceanography (oxygen, temperature, pH proxies), and ecology. My dissertation linked biogeographic patterns to extinction physiology, extinction and climate change; my postdoc extends this to invasive species and metabolic index modeling in the past ~125k years to the present.

03

Stratigraphy & Fieldwork

Reading rock sequences in the field to reconstruct ancient environments, collecting specimens, and systematically identifying fossils to build the primary datasets that everything else depends on. The numbers only mean something if you know what you're counting.

04

Data Visualization & Science Communication

Translating high-dimensional paleontological datasets into accessible visual narratives for scientific publication, public outreach, and policy-relevant storytelling. Fluent in R, Quarto, learning Python, and custom web-based visualization.

Research across time

Multiple timescales.
One through-line.

I study how ocean life survives Earth’s worst catastrophes in deep time.

I aim to understand what traits tip the balance between extinction and endurance by using physiology, ocean conditions, and evolutionary history to explain who survives global crises and how.

The history of visible life

What drives global taxonomic homogenization in deep time?

Examining the history of marine invertebrate life to determine the contributions of climate change and extinction to community compositional similarity. Now in review at Proceedings B.

The end-Permian Mass extinction · ~252 million years ago

The end-Permian extinction & "The Great Dulling"

After the largest mass extinction in Earth's history, marine ecosystems became strikingly similar worldwide, what we called "The Great Dulling" in Stanford Magazine. Organisms that could tolerate warmer, lower-oxygen oceans expanded globally.

I also spent a field season in Saudi Arabia collecting and then systematically identifying bivalve fossils from directly after the extinction event.

Humans or nature?

Current projects shift to conservation paleobiology, where I utilize my interdisciplinary tools in palebiology, physiology, and oceanography to quantify how oceanic changes have been, and continue to be, reefs and impacting benthic marine communities.

Baselines for future predictions

By examining data at multiple temporal and spatial scales, I aim to understand how the traits that helped organisms survive past environmental change will help them survive future ones.

Teaching

I love to teach.

So far, I've taught university level classes that encompass a wide range of students from freshmen majoring in humanities to PhD students in paleobiology; community college classes in physical geography and climate change; undergraduate-level introductory courses in paleobiology; and more!

My teaching philosophy is all about creating engaging, student-centered learning experiences, and it fills me with great joy to help teach and mentor future generations of scientists from all backgrounds about the oceans, the history of life, and the world around them while giving them applicable skills to tackle this rapidly changing world.

I've had the chance to teach and assist in courses on the coevolution of life and Earth, paleobiology, macroevolution, climate change, and mass extinctions, and have prepared for courses in oceanography, marine ecology, geology, and biogeography.

A classroom activity I created

Survive the Great Dying

Here's an example of a game I created, using publicly available resources, for the Sixth Mass Extinction (and the Other Five) class which explore the modern and past biodiversity crises. In this game, students vote on a variety of choices based on things they learned in class to help their creature survive the end-Permian mass extinction. Contact me for more information about this game!

Rules: Get at least 500 points to survive the end-Permian mass extinction. Vote on Polleverywhere. For each question, the answer with the highest submissions will be chosen.

One of my goals is student outreach within paleontology, so that everyone feels like they belong.

Outreach & Teaching

Science belongs
to everyone.

As the first female Saudi paleontologist, I am committed to broadening who feels welcome in the geosciences — through mentorship, public writing, and being visible where I wasn't expected to be.

01

DEEP Awards — Paleontological Society

For 3-4 years of my Ph.D. career, I happily volunteered in multiple positions with the Paleontological Society. I have a particular interest in making our field more welcoming to everyone, particularly if they are students or just starting out in their careers. With the help of my peers and friends at the Paleontological Society, I was able to create the DEEP awards, which award students and early career members for their efforts in enhancing the experiences of people who engage in paleontology and making paleontological information easier to access. The award grants them honoraria, plaques and memberships to the Society and making it a welcoming field. We honored them in a DEEP Awards celebration that had a fantastic turnout (more than 100 attendees out of an expected 70), which truly displayed how much the Society cares about these initiatives.

02

Stanford S.U.R.G.E. mentorship

Stanford's SURGE program aims to support the undergraduate experience of students across the United States by recruiting bright, talented undergraduates who might not otherwise have the opportunity to conduct research. In 2022, I had the pleasure of mentoring two undergraduate students, and helped with mentoring a BioX intern and 4 high school interns at the Payne lab!

Art & Creative Work

Science and imagination,
intertwined.

I draw digitally and with charcoal! I like to live-sketchtalks, make portraits in Procreate, and produce science illustrations. My team won top video for best storytelling at Stanford's BioX 2020. And, my creative magnum opus is a high fantasy novel I'm writing, woven through with biology and geology elements and a blend of my own culture.
