We had a great time at BPS 2026! Sad to conclude my time on the Theory & Comp subgroup committee but I enjoyed that service and made new friends along the way. Until Philly in 2027!

Insights into the Electronic and Structural Properties of Cellulose and Amylose: A Comparative Force Field Study
Amylose and cellulose are important biopolymers with diverse applications in biotechnology and materials science. Understanding their structural, dynamic, and solvation properties at the molecular level is critical for harnessing their potential. This study investigates the electronic and structural properties of single-chain cellulose and single- and double-chain amylose in aqueous solution using molecular dynamics simulations with both nonpolarizable (CHARMM) and polarizable (Drude) force fields. CHARMM simulations show stable hydrogen bonding between amylose and water, higher glucose ring dipole moments, increased rigidity, adoption of chair conformations, and less variation in dihedral angles. In contrast, Drude simulations captured dynamic electronic polarization, enhanced conformational flexibility, and resulted in heterogeneous inter- and intramolecular hydrogen bonds. For cellulose, structural and solvation behaviors were largely similar between CHARMM and Drude. These findings highlight molecular interactions and solvation dynamics of amylose and cellulose, with potential relevance in materials science and biotechnology.
First article of 2026! Happy to have our first real foray into carbohydrates out in J Phys Chem B. Excellent work by PhD candidate Esmat Mohammadi.

Excited to share a new update to the Drude polarizable force field - phosphorylated amino acids! A long-term project that took quite a bit of effort. Great work with PhD student Laura Gil Pineda, former undergrad Candace Miller, and @alexmackerell.bsky.social

2. Focus on people. When recruiting, itβs sometimes less about credentials and more about attitude. Iβll gladly take a student with no prior experience but a great attitude and desire to learn over one that has lots of technical skills but poor work ethic or attitude.

1. Start small. It is tempting to dive in and shoot for some huge research goal like youβve had in well established labs. Not going to work starting out. Do small things that will help you build toward realizing that larger vision. Funding and publications wonβt come right away but will eventually.

75 years of scientific discoveryβnow on the chopping block.
Trumpβs 2025 budget proposes a 56% cut to the NSF. Over 1,000 grants terminated. 37 divisions abolished. Funding frozen.
This isnβt just recklessβitβs a war on knowledge, a war on progress.

This is so important. Visual consistency takes the fatigue out of reviewing. I always use bold section headings and only underline short, key phrases. No italics except organism names (I find italics taxing to read in long blocks). Text boxes to summarize key concepts/questions for visual impact.
