During the month of July, members of Qiu lab (including the PI) will be responsible for the following:  
# Performing a careful sweep of the common seating, eating, and food preparation areas each Monday, Wednesday, and Friday. The purpose of this sweep is to do some light organization/cleaning and to identify persistent cleanliness problems that should then be reported (via the lab’s PI) to myself and Elizabeth Cohn (ec2692@hunter.cuny.edu), and the collective PIs of the floor.

July 2021

  • Belfer housekeeping duties: During the month of July, members of Qiu lab (including the PI) will be responsible for the following:
  1. Performing a careful sweep of the common seating, eating, and food preparation areas each Monday, Wednesday, and Friday. The purpose of this sweep is to do some light organization/cleaning and to identify persistent cleanliness problems that should then be reported (via the lab’s PI) to myself and Elizabeth Cohn (ec2692@hunter.cuny.edu), and the collective PIs of the floor.
  2. Throwing away any personal food (and personal food containers) left in the refrigerators beyond 5 pm on each Friday.
  3. Keeping general tabs on the bathrooms of the floor to ensure cleanliness. Persistent cleanliness problems that are unreasonable for the WCMC custodial staff should be addressed by the members of the floor.
  • July 2, Friday. Field trip

Project 1. Borrelia genomics

Transcriptome-table.png

Project 2. Design algorithms for vaccines

  • Participants: Dr Saad Mneimneih (CS Department), Brian
  • Questions & Goals:
    • Generalized algorithms for antigen with arbitrary tree shape
      • Data set 1. Neutral evolution (with exponentially distributed branch lengths). Binary strings (L=100 bits) evolved from a coalescent tree of 20 leaves. Simulated with rcoal(20); rTraitDisc; simSeq(). code from previous work
      • Data set 2. Two major clades. HA sequences from fluB
      • Data set 3. Four major clades. Dengue
      • Data set 4. Star-shaped tree, driven by recombination. OspC
      • Data set 5. Multiple major clades. vls cassette in Lyme species
    • Combination algorithms
    • Naive Bayes models to integrate immunogenicity data
    • Natural language models to improve structural stability (see Project 4 below)
  • Reading list

Project 3. HIV compartmentalized evolution

by Lily
  • Participants: Lily
  • Questions and goals
    • Do HIV evolve cell type tropisms within the host? Specifically, the Neural(N)-tropism vs T-cell(T)-tropism?
    • Build a classifier of N-tropism HIV subtypes
    • A presentation for an HIV conference in October
  • Reading list
  • Data sets
    • ~500 sequences of env genes from 15 patients
    • 2nd time point single-cell genome sequences for some of the patients
    • Experimentally verified N-tropism subtypes
  • Approach
    • Evolutionary mechanisms: mutation, recombination, and adaptive selection
    • Homoplasy index as a measure of compartmentalization? Randomization to obtain p-values of HI.
    • Evolutionary rates & signature (BEAST)
    • Tests of natural selection (PAML site models, branch-site models & MK analysis)
    • Phylogenetic analysis: tree per individual; supertree; haplotype networks (per individual)
    • Simulated compartmentalization

Project 4. Natural Language models of proteins

  • Participants: Eamen, Roman, and Edgar
  • Questions & Goals
  1. Learn, implement, and compare the existing tools
  2. Fine-tuning for OspC, to be integrated with the centroid algorithm
  3. 2nd-generation centroid design: k-means algorithm (with applications to vls, Dengue, flu B)
