Published, reliable recent research on aerodynamics and or training with power metrics as key focal

The people paying for wind tunnel testing generally would not benefit
from giving the info away. Tour Magazine (germany) does regular aero
testing of equipment, but I'm not aware of them testing riders for
position.

The articles and forum here are good places to find info on that:

We previously reported that a mathematical model could accurately
predict steady-state road-cycling power when all the model parameters
were known. Application of that model to competitive cycling has been
limited by the need to obtain accurate parameter values, the
non-steady-state nature of many cycling events, and because the validity
of the model at maximal power has not been established. PURPOSE: We
determined whether modeling parameters could be accurately determined
during field trials and whether the model could accurately predict
cycling speed during maximal acceleration using forward integration.
METHODS: First, we quantified aerodynamic drag area of six cyclists
using both wind tunnel and field trials allowing for these two
techniques to be compared. Next, we determined the aerodynamic drag area
of three world-class sprint cyclists using the field-test protocol.
Track cyclists also performed maximal standing-start time trials, during
which we recorded power and speed. Finally, we used forward integration
to predict cycling speed from power-time data recorded during the
maximal trials allowing us to compare predicted speed with measured
speed. RESULTS: Field-based values of aerodynamic drag area (0.258 +/-
0.006 m) did not differ (P = 0.53) from those measured in a wind tunnel
(0.261 +/- 0.006 m2). Forward integration modeling accurately predicted
cycling speed (y = x, r2 = 0.989) over the duration of the
standing-start sprints. CONCLUSIONS: Field-derived values for
aerodynamic drag area can be equivalent to values derived from wind
tunnel testing, and these values can be used to accurately predict speed
even during maximal-power acceleration by world-class sprint cyclists.
This model could be useful for assessing aerodynamic issues and for
predicting how subtle changes in riding position, mass, or power output
will influence cycling speed.
