  The millisecond pulsar MAXI J1816-195 was recently discovered in an outburst
by MAXI in 2022 May. We study different properties of the pulsar using data
from NuSTAR and NICER observations. The unstable burning of accreted material
on the surface of neutron stars induces thermonuclear (Type-I) bursts. Several
such thermonuclear bursts have been detected by MAXI J1816-195 during its
outburst. We investigate the evolution of the burst profile with flux and
energy using NuSTAR and NICER observations. During the NuSTAR observation, a
total of four bursts were detected from the source. The duration of each burst
is around $\sim$ 30 s and the ratio of peak to persistent count rate is $\sim$
26 as seen from the NuSTAR data. The burst profiles are modelled using a sharp
linear rise and exponential decay function to determine the burst timing
parameters. The burst profiles show a relatively long tail at lower energies.
The broadband time-resolved spectra during the burst periods are successfully
modelled with a combination of an absorbed blackbody along with a non-thermal
component to account for the persistent emission. From our modelling results,
we are able to estimate the maximum apparent emitting area of the blackbody of
the neutron star to be $\sim$12.5 km during the peak of the outburst and the
maximum distance to the object to be 8.7 kpc. Our findings for the mass
accretion rate and the alpha factor indicate the stable burning of hydrogen via
a hot CNO cycle during the bursts.
