Working on a revision for a biology-focused paper, and somehow ended up with proving propositions and lemmas 😅. Sadly, they all will need to go to the supplement.

New preprint on a new diversity-dependent biogeographic diversification model using deep learning. Joint work with my amazing advisor @landismj.bsky.social. Details of the paper in the comment section. #evobio www.biorxiv.org/content/10.6...

Decided to add some non-academic content to my personal site. Right now, it features personal photos of (mostly Indonesian) food I made, batiks, and (anime) figures! More here: sites.google.com/view/albert-...

Some of my favorites Indonesian Batiks en.wikipedia.org/wiki/Batik_i...

Last January, I gave a seminar talk at Indonesia's National Research and Innovation Agency on mathematical and statistical approaches to study evolutionary processes. The slides (in English) are available on my website for anyone interested: sites.google.com/view/albert-... #evobio

New preprint modeling biogeo diversification of Hawaiian Kadua 🌱🏝️🌋 w/ @ca-naturalist.bsky.social @sswiston.bsky.social @fabiology.bsky.social @phylogeny.bsky.social Warren Wagner, Bruce Baldwin, Ken Wood @ninaronsted.bsky.social @fzapata.bsky.social biorxiv.org/content/10.64898/2025.12.16.694722

New preprint on a new infectious disease model with visitor dynamics using phylogenetic approach 😊

Giving a public lecture to math students and lecturers, introducing the use of mathematics in evolutionary biology and infectious disease modeling. It's good to contribute back to my almamater in Indonesia. For Indonesian viewers, my materials can be accessed here: sites.google.com/view/albert-...

An honest mistake by mathematician 😆

Some screenshots from this year's Phylomania - great to see familiar faces and names, even through a virtual screen :) Also, my talk can be accessed here: sites.google.com/view/albert-... (preprint is hopefully out soon) #evobio

Phylomania will kick off in a few hours. Will be presenting my work with @landismj.bsky.social on a biogeographic model wiith diversity-dependence for modeling species diversification 😊 www.maths.utas.edu.au/phylomania/p... (By the way, Joe Felsenstein is among the presenters) #evobio

It always feels nice to be able to give something back to your alma mater. It has been 10 years since an 18 yo me completed his undergraduate and got introduced to the wonderful world of evolutionary biology and phylogenetic inference 😊 #evobio

Today at WashU’s EEB seminar, I presented a new species diversification model that incorporates regional species diversity into rates of evolution through time (a joint work w/ @landismj.bsky.social). Slides here: sites.google.com/view/albert-... Preprint hopefully will be here this month #evobio

[1/11] A quick rundown to our density-dependent biogeographic model of species diversification below: P.S. Preprint coming up soon! #Evol2025

What a blast attending my first in-person Evolution meetings! Had the opportunity to present our work on: 1. A new biogeographic model of species diversification that accounts for species richness. 2. Phylogeography model for infectious disease transmission with visitor dynamics. #Evol2025

Honored to be elected as a member of the @sigmaxi.bsky.social - one of the oldest honor societies in science. Thank you to the two anonymous committee members for the nomination!

About 11 years ago, I received financial support from Van-Deventer Maas Indonesia (VDMI) to fund my undergraduate studies. Fast-forward to 2025, I will be sharing about living and working abroad from a perspective of an international scholar. Thank you VDMI for organizing this event! #outreach

Our article on "matrix-analytic methods for the evolution of species trees, gene trees, and their reconciliation" is recently published on Methodology and Computing in Applied Probability journal. #evobio Link here: link.springer.com/article/10.1...

Earlier this year my advisor @landismj.bsky.social and I published this cool work at BMB; looking at applying diffusion in macroevolutionary context for state-dependent diversification models to learn about evolutionary patterns that these models produce. #evobio www.smb.org/news/13402507

Just recently joined Bluesky to connect with phylo community here. So, here is my first trace on this platform :) I am a postdoc in Landis lab at WashU and a mathematician by training with interests in models of species diversification and phylodynamics. #evobio sites.google.com/view/albert-...
