I've generally got a habit of making very large posts.. but in this case, the topic is vast enough that if I try to go into detail I'll end up only covering a portion of one aspect, and will likely run out of time before getting to the rest.
To help you, I'm simply going to suggest some areas of research that will likely serve you in some way.
In relation to psychology (as a science) and how it relates to spirituality, you'll likely find benefit in 'parapsychology'. Two links that could help you get started are organisations that are dedicated to the field:
http://www.aiprinc.org/
http://www.parapsych.org/
And a link that was provided by another member here is:

While more of a philosophical field, you may find some correlations between spirituality and metaphysics

Finally, there's an entire field of spirituality that deals with mathematics; called Sacred Geometry. This also considers aspects of physics, time/space, dimensions, DNA, consciousness... and much more.

The links above only give a brief overview of the fields, and it's likely you'll need to do further (extensive) research into each of them to improve your understanding of how each can be applied in a scientific way.
Additional fields that could be of interest are:
Crystals, in particular orgone generators:

Scientific research into astral projection:

The pyramids and other sacred sites in terms of location/dimensions (this is a very 'dry' speaker, but the information is good):

How technology/automation is removing our need to work (and potentially allowing us to pursue more spiritual paths):

How sound frequencies can be used to affect our physical and subtle bodies:

How sonics and ultrasonics can be used to kill viruses:

How ultrasonics can result in 'ghost sightings':

How chakras are linked to physical organs. Keep in mind that there are often differences about which chakra performs which role and where they are linked depending on who's providing the details:

Healing, in this example with chi energy:

(another example where we can see an ultrasound of a tumor being healed:

It likely goes without saying, that there are many other fields of research and study into spirituality (in relation to science). Everything from reading minds, remote viewing, healing, manipulating the weather/temperature, levitation, extrasensory perception... the list can go on. It mostly depends on your area(s) of interest.
If you have any questions, or would like me to expand on any of the above, please let me know.
