Pedro Tamaroff

I am currently a PhD student at Trinity College Dublin under the direction of Vladimir Dotsenko (09/2017-09/2021). I did my undergraduate studies at the University of Buenos Aires, and wrote my thesis under the direction of Mariano Suárez-Álvarez. You may know me from math.SE. Or you just may not. Here's a picture of myself.

My curriculum vitae is available here. Last updated October 2020.

Research interests

I am interested in homological algebra, homotopical algebra, algebraic homotopy, effective homology, higher structures, operads, representation theory and combinatorics.

  2. Endofunctors and Poincaré–Birkhoff–Witt Theorems, with Vladimir Dotsenko. Published in Int. Math. Res. Notices, rnz369.
  3. Minimal models for monomial algebras. Accepted for publication at Homol. Homotopy Appl.


  1. Differential forms for smooth operadic algebras, with Ricardo Campos.
  2. A spectral sequence for tangent cohomology of algebraic operads, with José Moreno-Fernández. Submitted for publication.
  3. Derived Poincaré--Birkhoff--Witt theorems, with Anton Khoroshkin. Submitted for publication.
  4. Finite generation for Hochschild cohomology of Gorenstein monomial algebras, with Vladimir Dotsenko and Vincent Gélinas. Submitted for publication.
  5. The cohomology of twisted coalgebras. Submitted for publication. This article is based on my MSc thesis, which you can find a few lines below.

Upcoming and recent events

Talks and slides


I am/was a teacher assistant and/or graded for the following courses in TCD. Boldfaced courses are currently active. You may find further information by following the links provided. I also participated in MA4492, where students produced final year projects under the supervision of Vladimir Dotsenko.

Note that starting Michaelmas term 2019, course codes have a new format! In particular, note course MA2323 has new code MAU22200 and new name.

Homework for MAU22101 (Michaelmas 2020)

The following are the questions and solutions for the weekly assignments for MAU22101. Solutions due on and uploaded weekly on Thuesdays at 4:00 pm. Assignments can be found in the TEAMS channel for the class.

Former assignments. [1], [S]; [2], [S]; [3], [S]; [4], [S]; [5], [S]; [6], [S]; [7], [S].

I am a casual blues and swing dancer, and you can find me either struttin' with the people of Downtown Blues or swinging out with the folks at Swing By. If you're curious, be sure to check their classes, there's always room for one more.


"We all come from somewhere. We carry that place with us wherever we go. That never leaves our heart. Not entirely. But none of us can predict where our voyage will lead. We may suffer losses along the way. But we can hope to learn and grow from those experiences and from those who accompany us in our journey." Saru in The Sound of Thunder.

"Connection, joy, love, and resurrection: with these words, the path becomes clear for a moment, and then disappears. If I have a path I am still searching for it. We all are. That's how we find our way. By choosing to walk forward. Together. And if there is a greater hand leading us into uncertain future I can only hope it guides us well." Michael Burnham in Saints of Imperfection.

"We are deeply social and deeply instinctual animals, so much that our well-being depends on many things we do that are hard to explain in an intellectual way. That is why you do well to follow your heart and your passion. Bare reason is likely to lead you astray. None of us are smart and wise enough to figure it out intellectually." Bill Thurston in this MO post.

"Attention is the reader’s gift to you. That gift is precious. And finite. And should you fail to be a respectful steward of that gift—most commonly, by boring or exasperating your reader—it will be promptly revoked.

Once a reader revokes the gift of attention, you don’t have a reader anymore. Then you become a writer only in the narrowest sense of the word. Yes, you put words on some pages. But if your reader has disappeared, what was the point? How is your writing more valuable than a random string of characters? Like the proverbial tree falling in the woods, no one’s there to notice the difference." Matthew Butterick in his book on typography.
