Want to come do a postdoc with us?
Weβre interested in how sensorimotor function is carried out by the cells and circuits of the spinal cord. We have an awesome team, lots of cool techniques, and weβre open to new ideas/approaches/connections. Get in touch!

Iβm recruiting new members to the Farrell Lab this summer. We will have space for 1 postdoc (since Abhinav is leaving to start his own lab at U Arizona!!) and 2 postbacs, since my current two will leave for PhD programs at the end of the summer. More details in thread:

ESFS: A Noise-Resilient Framework for Feature Selection and Marker Gene Discovery in Single-Cell Transcriptomics
Single-cell RNA sequencing (scRNA-seq) has transformed our ability to resolve cellular heterogeneity, but extracting meaningful signals remains challenging due to technical noise, batch effects, and the limitations of current feature selection methods. We present Entropy Sorting Feature Selection (ESFS), a modular, user-friendly framework that captures multivariate gene expression relationships without imputation or denoising via latent spaces. Across diverse datasets, ESFS improves interpretability and reveals biology missed by standard workflows: identifying coherent developmental programs in eight independent human embryo datasets without batch integration; resolving spatial gene expression in mouse colon obscured by conventional analyses; distinguishing shared and tumour-specific microenvironments in glioblastoma; and disambiguating spatial, temporal, and neurogenic programs in the developing mouse neural tube. By operating in gene expression space, ESFS produces interpretable, biologically meaningful outputs while reducing artefacts introduced by feature extraction. These results position ESFS as a powerful means to uncover relevant molecular signatures in noisy, high-dimensional transcriptomics data. ### Competing Interest Statement The authors have declared no competing interest.

I am very happy (and a bit scared) to present to you what we have been working on over the last 4 years. This manuscript is exactly what I dreamt of when I started the lab and I could not be happier and prouder of the outcome!

Ontogeny of the spinal cord dorsal horn
The dorsal horn of the mammalian spinal cord is organized into laminae where each layer is populated by different neuron types, has distinctive circuit connections, and plays specialized roles in beha...
Excited to share @rbrianroome.bsky.social βs beautiful paper on development of the dorsal horn of the mouse spinal cord @science.org
This is how the anatomical organization and cell types that process pain, touch, body position and more are laid down.

Join us for Fall 2026. In our group, you can run studies from human behavior and neuroimaging, to large-scale NHP ephys, and join them up with a robust computational foundation. Bonus: you can help build the reading list.

Hello π«π·
Iβll be doing a mini-sabbatical in the lab of the amazing @clairewyart.bsky.social at the ICM in Paris. If you study motor control, spinal cord biology, evo/devo of behavior, let me know if youβd like to connect!

Oh yeah. In the lab, weβve discussed every common definition because we study gap crossing jumps and the propulsive phase is likely the closest. I believe in frogs it is truly ballistic but mammals can tune it a bit

Yep, Iβve actually discussed it with him and stick by my argument that this would work great for some types of motor control but there are clearly ancient/core movements that this doesnβt explain well

Totally agree. As you know, I favor thinking of motor control principles varying depending on behavior and animal.
Actually, to take inspiration from Mark Latash, his translation of Bernsteinβs book is one of my favorite descriptions of how this could all work together

But this is very different, no? Doesnβt he propose that the final limb location/configuration is the control parameter? This may be true for some movements (eg visually guided forelimb) but I doubt it is right for others (eg ballistic hindlimb)

For example, we can elicit a multi-joint flexion synergy by stimulating some spinal neurons and that works regardless of limb starting position

Ah, I understand. But I think the stimulation studies that evoke synergies are a better case here than the ones that observe movements or EMG and do dimensionality reduction.
